Raytracing is pretty new and not really worth it right now but it can add a lot more to a game just by simply adding real-time reflection and shadows to them. And it can also probably function as real-time sound tracing for more immersive sound in the future.

I think people are being too hard on it cuz it makes them look cool.. not accusing that of you personally but I get that vibe alot from some people who are like 'it's a dumb meme' or whatever. My logic is comparing RT on/off to 2k and 4k pixels. I personally don't notice 4k over 2k that much unless I'm sitting really close to a relatively large monitor and scrutinize it. Furthermore, 4k hits your performance MORE than RT (for series 3x and 4x nvidea cards at least, which you will have if you want the RT most likely), and then the monitor you have is GOING to have worse refresh rate and stuff at 4k than 2k, unless you fork over an extra GRAND (which would enable you to get a graphics card that CAN handle RT at over 200fps at 2k or whatever) over a good 2k monitor. Nobody says 4k is a meme, but I think 4k is much more meme-status than RT Imo.. when RT is actually implemented

The problem for RT being adopted by game developers instead of using rasterisation is not the artists, but the business model. Imagine you're the CEO and you're asking your project managers how the developers are doing with the latest game. They say they've ditched rasterisation and are solely using RT which has cut down development time/costs by about 20% because they don't have to waste so much time faking light sources with rasterisation. So far so good. You ask if there are any downsides to this approach: Well only 20% of your potential market for that game can afford graphics cards powerful enough to run RT, so you're probably going to lose 80% of sales. See the problem? That's why RT being useful for artists is never going to gain traction in the gaming world while ever most of the market can't afford graphics cards that can run at max settings with RT on.

One my biggest problems with ray tracing is how some scenarios make it terrible difficult to tell the difference but there is still a huge performance hit. Even with still images. Like walking somewhere outside with heavy clouds and no highly reflective surfaces nearby. There won't be much shadows and reflections to ray trace. That's why I feel some devs tend to overdo reflections and make everything look shiny wet or chrome coated. Which ends up looking not natural at all. One of the best example is Hogwarts castle. Some floors look ridiculous with RT and I much prefer the rasterized reflections.

[@Chronically_ChiII]

Rasterized have better reflections in that game than ray tracing. It's kinda pathetic, honestly

[@ninjatogo]

Perfect reflections are easier/computationally cheaper to ray trace compared to rough or varied roughness reflections, so until we get faster hardware across the board, developers are going to focus on the cheaper effects.

[@invertexyz]

Part of the issue with that is most devs don't implement fully raytraced environments, because it's just so damn expensive. Most of the time it's just raytraced shadows, MAYBE reflection and on the very rare occasion global illumination, and only then does it really start to make a difference, as rasterized shadows and reflections had already become quite good hacks (but the workflow for those hacks is much worse than doing raytracing. Games should have to state the level of raytracing, instead of just "this game is raytracing enabled".

And what about GI? Especially in a dynamic scene? Now don't tell me you don't even know what GI means

[@MistyKathrine]

[@Ivan-pr7ku]

For the last 20 years, developers and graphics designers have mastered the approximation of many rendering effects with good-enough quality for real-time graphics. Most of the reflections can be done with portal rendering, planar or spherical mapping and even scree-space methods, where appropriate. Shadow maps have already been perfected in pretty much every engine out there. Dynamic GI is one area where real-time RT is bringing tangible benefits and game devs have chronically struggled to come with universal solutions using various light transfer hacks. For the time being, cost-effective and carefully tuned hybrid implementation of RT is the way to go.

[@5000Seabass]

This is the only correct answer

[@existentialselkath1264]

Planar can only be used on flat surfaces and is more expensive than raytracing unless it's used very sparingly. Cubemaps are incredibly inaccurate and can only approximate the general lighting conditions. Screenspace is full of artifacts, breakup, temporal instability, and can (by definition) only reflect objects on screen. Reflections are by far the worst part of rasterised visuals. They're messy, full of artifacts, don't make logical sense, and are just terrible. Even games like forza still don't have cars reflecting themselves which makes everything 'glow' because internal reflections are impossible without the mess of ssr

4:04 - That "mushroom shaped tree" in the center frame really captures my feeling on RTX right now. The shading on the left is just soooo much better, looks very Pixar-esque. I think raytracing right now might kind of be like bloom back in ~2007. Meaning that it feels like games just "turn RTX on" blindly, and it ends up hurting the art direction more than anything else. Maybe after some time, more devs/artists will be able to utilize it more effectively and with more intention, but yea, as it stands right now I think RTX tends to hurt games more than it helps. Like even with the Witcher 3, there's something about how RTX is interacting with the textures, or bump maps, or something like that just sticks out to me as "not right".

[@G7ue]

I agree. Its kinda just tacked on, and not thought out in most games. However I wills say that Fortnite has a good benefit from it. That tree is just a bad comparison because of the change in the lighting direction. In the rasterization view, the lighting is coming from the right, highlighting the shading and depth. Where as in RTX, its coming from behind the player, hiding the shading behind the tree and making it look more flat. Honestly this entire video was pretty bad at showing off what RTX is even for. Static, open environments are the worst place to showcase RTX. It is most beneficial with interiors, and dynamic environments, hence why I say Fortnite is a good choice for RTX. Lots of dynamic interiors spaces.

One of the biggest advantages of RT doesn't even have anything to do with fidelity.

[@holad-jlsegovia-423]

Ray tracing can look incredible, depends of the implementation but... my main issue is that developers seem to have forgotten about their art style and instead rely too heavily on RTX, for example I've seen many recent games that use RTX for reflections to make bodies of water look pretty but when it's disabled, there will be no reflections whatsoever, not even a cubemap or anything or other games that use it for it's shadows but when RT it's disabled it will have really bad looking and jagged shadows that had no care or effort into their implementation. It kinda shows how some devs rely too much on the technology and use it as a buzzword to sell morr copies

[@rvnx]

I like RT. But I don't actively use it in every game that has it. It is nice to look at, and depending on the game it can make a huge difference in looks. But I feel like especially on modern games that utilize modern rasterized graphics and shaders, you often run into an area where the visual improvement simply doesn't justify the immense performance cost. Some older titles such as Portal, Half-Life or Quake that got a RT-enabled port, RT can breathe a completely new life into the game, together with an immensely more convincing atmosphere despite the otherwise aged looks due to how simple lighting was constructed and calculated in older engines. They also have the available performance headroom to make RT play- and viable. IMO This is where RT really shines, and I hope that with the advent of NVidia Remix we can see a lot more of such examples.

A lot of people will become nostalgic toward the hand crafted and artistic deliberate nature of rasterized graphics... You can actually tell that this is already happening when people play new games that are developed in old school game engines, as developers are painstakingly deliberate with everything they do in level design. Many people feel, myself included, that a lot of the artistic talent is lost in games when we start to rely on large photogrammetry scanned libraries like Quixel, in which assets are copy and pasted from a library rather than being hand crafted. Same goes for lighting, Just have a look at Ion Fury and how deliberate the lighting is. designers even construct the map around the lighting, putting it into the actual vectors of the map. or let say Wrath: Aeon of Ruin which uses the Quake 1 engine. It looks so moody, and brilliant, however it still uses GPU and game engine tech from 1996.

I'm not even kidding, there are some game trailers out there that have the "RTX off / RTX on" comparisons, and I literally cannot see _any_ difference between them. This even though these trailers are supposed to specifically demonstrate the difference! Of course then in games themselves it can be difficult to see where the "raytracing" is supposed to be happening. There are some games where it's extremely obvious and cool (such as Control), but then there are other games where it's a real game (hah!) of "spot the difference". For example Deathloop, at least on the PS5, is supposed to have raytracing support. However, the _only_ effect that turning it on has is to tank the framerate so low as to make the game literally unplayable (and no, I'm not one of those snobs who thinks that 30 FPS is "unplayable". I'm not exaggerating here. Try it if you don't believe me. The game literally cannot be played when "raytracing" mode is turned on. The input lag is astonishingly bad. It would be bad even for some slow-paced turn-based tactics game, it makes it literally impossible for a fast-paced first-person shooter.) And the kicker is: There literally is no visual difference between the normal and raytraced modes. Again, I'm not exaggerating. I have taken screenshots of the same locations in both modes, locations that ought to have some differences in them (significant reflections, shadows, lighting, etc) and switching back-and-forth between the screenshots shows literally no difference. Clearly the game is doing _something_ because the framerate is so horrendous in the "raytracing" mode, but visually there is literally no difference. Such a scam. (And the worst thing is that I bought the game precisely because of the alleged raytracing support, which is rare on the PS5.)

Main benefit of ray tracing is it takes less work on the development side to make things look good. But since most people aren't using raytracing it doesn't really matter cause they'll still make it work with rasterized rendering anyways. With ray tracing I can just throw a few lights in the scene and bam done, but rasterizing it's a bit more work if you want it to look good (a lot of developers don't put the work in to make it look good.

The thing is too... games are art. Art is about illusion. Some of the most dramatic and beautiful scenes and moments in gaming, are built around heavy use of illusion; sky boxes with pre-rendered backgrounds, levels intelligently culling detail so that they can optimize performance but imply far more than is really there, tricking the imagination. Just look at some of the crazy stuff they did to make Dead Space 2 work, for example, with entire level cityscapes appearing or disappearing in the background... This is the real artistry of gaming. To take what isn't even remotely real, and make the player think it's real, and to do so in an efficient way. Remember when Star Citizen was proud of the fact that it had re-invented the way FPS games handle the camera, and had stuck a camera in the character's actual head, and then discovered that the character's movements were chaotic and unpleasant to look at, so they created a new way to stabilize the camera in the character's head so that it looked... uh... like the old FPS cameras did? That's RTX. Flinging a lot of processing power at a problem that was already solved by the artist. I'm playing Metal Gear Solid 1 at the moment, the PS1 version emulated. I'm not doing anything fancy to the visuals; I have a CRT filter on, that's about it. You know what really strikes me about the game? The lighting is beautiful. Oh, I can see that it's not "real" lighting; if I were to guess, I'd say most of the lighting is baked into the textures themselves. But the choice of colours, the striking way the game uses neutral shades of grey and blue and green to somehow accentuate what matters, and make things stand out, even when the colour palette is so subtle? Beautiful work. Distinctive, and memorable. And very, very deliberate. What is it, exactly, that RTX offers... except the automation of that which artistry had already conquered? And through that automation, are we not in danger of losing that deliberate artistry? In the Witcher 3 example - the raytraced version demonstrated that, if we're going by "realistic" global illumination, the reflective qualities of something simple as pale stone... results in the lighting getting washed out; no more high contrast shadows, serving to draw attention to the player's movements through the world... just a whole lot of glare. And sure, that glare is realistic. But games aren't meant to just be "realistic". The lighting of a scene is supposed to be like the lighting of a movie, or a painting; it's supposed to serve specific artistic purposes, not just capture how things should realistically look.

[@Avalan666]

Path-traced Cyberpunk 2077, why not include it? It looks jaw-dropping awesome but yeah, the performance hit is massive and yet rtx 4060 can run it (with dlss frame generation) at 60fps. So we can already see how much better ray-tracing is compared to rasterisation.

[@invertexyz]

2:33 To clarify, raytracing usually isn't rays from the light sources, but actually done in reverse, where for each pixel on screen, a ray is traced from the camera/eye out to those points and bounced until they either hit a light source or don't, and then propagate that information back down the path. This drastically cuts down on costs since you only trace what would actually be visible. But, it isn't 100% physically accurate, though close enough. When you want high physical accuracy, that's when "path tracing" comes in, which is usually the term used when the tracing will be happening from the light sources. This ensures lighting even from far distant away sources is bounced and scattered all over the objects, but is quite expensive. Cyberpunk just implemented pathtracing in their update today which is exclusive to 40 series cards and basically requires a 4090 running the game at a very low resolution with the newest DLSS upscaling to get acceptable framerates haha

[@張彥暉-v8p]

As an illustrator, i can easily tell which side is the the raytraced one and RT GI/AO usually looks way better than rasterization GI/AO especially in open world title. If you are playing a single player game with 3080ti plus tier gpu then you should try the ray tracing IMO. Still no reason to use it in competitive games tho until we can get a 3090 tier mid range(50/60) gpu.

Guessed all 3 correctly, but I'm pretty sure the first 2 could at least fake the global illumination without raytracing, while on SotTR it was mainly the softness of the shadows, which can be done rasterized as well.

[@Ilestun]

Got a 4080, I don't activate RTX, the frame rate loss is not worth it. Reflexions and such have been pushed to a very high level with rasterrization.

[@nathandam6415]

This isn't correct. Reflections are actually worse for rasterization. The way reflections are often done for puddles and water sources on the ground rely on flipping the image around 180 degrees and basically filling in the reflection that way. It's very flawed. It doesn't show objects that aren't on the screen- if you looked down on a reflective surface and the view of trees disappeared from your line of sight their reflection would disappear. Secondly, reflections in transparent objects like glass also suffer greatly as rasterization relies on inaccurate cubemaps as an approximation and do not appropriately represent what is being reflected.

[@crestofhonor2349]

I do love ray tracing. It's a technlogy that's super interesting and will be the future of in game lighting for 3D games going into the future. It's just about how it's implemented. Normally it can solve lots of issues with games and lighting today that come with ambient occlusion, shadows, global illumination, and reflections that standard rasterization. Now whether I turn all the features on is up to me on a game by game basis. Cyberpunk and Metro Exodus Enhanced Edition will always be a great example of ray tracing and it's benefits. Once UE5 finally starts getting major releases in games ray tracing will become even more prevalent because Lumen can utilize ray tracing hardware to improve the quality of what they are doing and can apply to their Virtual shadow maps, Global Illumination and Reflections. Ray tracing is also well suited for both stylized graphics and photo realism assuming the artist can do it. Yes we are far away from fully ray or path traced games due to GPU performance in ray tracing but every new generation we inch closer and closer. I assume it will truly take over once the PS6 and Xbox whatever come out. It has a lot of potential but many people just don't know what really any graphical feature is, just whether or not it has a large performance impact and whether it's worth it.

[@DenverStarkey]

the thing about ray tracing is it's one of those technologies that only get the developers get hot and bothered over. most consumers don't understand what it is and they can't tell much diference like they could with say physX for example. so many think it will die out like physX did. mean while game artist often work between the game industry and the 3d movie industry so they are fully aware of what ray tracing is and it's benefits both on the visual level as well as the work flow level. it's been around since the begining of 3d technology so they are very familiar with transitioning to it. and that is why it WON'T fade away like physX did. in 3d movies it has been the "go to" lighting system from the get go , from terminator 2 to toy story. Ray tracing is the history of 3d rendering which is why it will be the future of game rendering going forward now that we actually got hardware that can process it in real time frame rates.

Wanted to downsize from full atx build with 3070ti and 21:9 monitor to something way smaller and decided to go full team blue with arc a750 and ray tracing was a factor in that vs a better card from AMD for the same price or cheaper.

@@MLWJ1993 A lot of people are also very used to the way graphics look in rasterization even though it actually looks weird when you get aware of the difference. Like I can no longer unsee that a lot of places in The Witcher 3 are lit like they are in direct sunlight even when they are not, but people I find often tend to not really compare how games look to real life but to other games. A lot of people for example complaining about surfaces being overly reflective with ray traced reflections would be surprised to see how reflective a lot of surfaces are when you actually pay attention to how light bounces in an environment. There are also some indirect benefits to Ray-Tracing that are maybe not clear just by looking at comparisons of games not made with it at there core, but a certain things like real time global illumination you get from Ray-Tracing actually does great things for allowing artists to more quickly iterate over scenes to make the lighting actually look good. I should also say just because a graphical features allows stuff to more accurately approximate real life doesn't mean it can't be used in more stylized art. Just because things get stylized doesn't mean that people don't care about things like anatomy, lighting etc. Those are all very important things even in stylization, so having access to easier to iterate upon and more realistic lighting methods does a lot for everyone not just people trying to make hyper realistic shit.

I would like to point out that most RT-enabled games are built to support both rasterizaton and ray tracing. This means a lot of software compromise. Look at metro exodus enhanced edition that was built to purely support RT. You get both visuals and performance. It's a considerable software limitation.

[@bananaboy482]

I don't think it's a software limitation as much as it's an art direction and time limitation. The issue is that the art directors, QA, and others all have to review and design every part of the game's lighting in every scene TWICE. Once with traditional shadow maps, probe GI, reflections, etc. Then another time with each RT effect enabled.

[@shadyti5]

@@bananaboy482 it is increased work, sure. I'll agree. But if you look at it most games that we take about when RT comes to the picture implement RT over rasterized techniques so it's playable on all hardware. Even if your using RT your wasting computation on preliminary calculations for rasterized lighting. Again, I'm gonna talk about metro exodus as my example, it has some pretty heavy RT (RTGI with infinite bounces, most other games just have reflections, shadows and lighting with 3 bounces.) RT on the gold edition is about as performant as youd expect which is to say, limited light bounces and low fps. Enhanced edition has its entire raster lighting ripped out and a pure RT implementation (with means you can’t run it on non-RT capable hardware.) The thing is this RT-only optimized approach runs the aforementioned heavy duty RT effects with performance that equals (if not exceeds by 1 or 2%) the raster version of the game. Considering game dev times, must of our so called RT-games are really raster games with RT slapped on top. That said, not everyone has the time or money to build an RT-only edition (there's a reason Meteo Exodus enhanced edition is the only game I know to have done this,) so until game engines embrace optimized RT-first lighting (or at least swapable lighting systems instead of overlapping lighting,) I'm not holding my breath for performance RT. P.S. I just wanted to put this out because I'm tired of hearing people say there's no difference (because the RT implementation is skin deep) or asking if it's worth the performance hit (right now, it depends on the game, but that's an optimization problem, not a raytracing one.) P.P.S. Typed this on my phone, to lazy to spellcheck

[@bananaboy482]

@@shadyti5 I don't think you understand what you're talking about. You're not wasting preliminary calculations on rasterized lighting as the game is still inherently rasterized. It's just using a lighting cache that's computed using triangle ray tracing. Also Metro Exodus enhanced edition runs near identical to the Metro Exodus original with RTX GI probes. The only difference is in the implementation of the lighting calculations using a surface cache instead of augmenting the original probe based lighting. In your words, Metro Exodus enhanced is exactly a traditional rasterized game with RT effects layered on top. It would be stupid to do it otherwise and have full ray traced direct lighting like something like Portal with RTX. It doesn't have to do with the developer time or optimization, building a BVH on the CPU and doing triangle ray tracing is always going to be very expensive without dedicated hardware acceleration, and even then we can see that that's very difficult. The improvements in ray tracing performance from the 20 series to the 40 series is almost none, they just added more cache to help speed it up.

The bulk of gamers are mostly maximizing a frames vs monetary cost function. RT increases monetary cost and decreases frames. It should be no surprise it isn't wildly popular.

Good rasterisation can visually look better than bad ray tracing and vice versa, and in the end it's a relatively small feature for the huge price point that comes with it. And lighting just like any other part of the graphical side of the game can be heavily stylised, like I really disliked how RTX looked on the witcher because it felt like the contrast was taken away with RTX and the stronger more contrasting shadows on the raster version hid some of the imperfections in the textures and models.

[@therflash]

Showing ray tracing examples outdoors isn't a very fair example, because a blue sky is dead easy to approximate in rasterization, and the bounced light isn't going to outshine it. Try some indoor areas lit by multiple light sources, throw in some reflective surfaces and the visual difference is massive. Also, in the last 20 years we've been trained to ignore what's in the reflections, because there's never anything useful to see in there. In ray traced reflections, you have an opportunity to see reflected things that you can't otherwise see on your screen, which can be an advantage.

[@NickP-ug2bl]

It's funny with the tests I chose rasterized every time. I guess I'm used to it. In some cases I even found it more natural looking. That being said when on a game it gives a little visual extra and it doesn't affect performance too much for my hardware I live it on. Like Doom Eternal for example, or Metro exodus. On Cyberpunk I never used it cause the game looks amazing already rasterized on HDR tv and the performance hit with RT is huge.

[@alkaholic4848]

It's not just about FPS in MP, it's the trade-off against other settings in SP. For example - If you can run RT on at 1440, but RT off at 4k; you're going to choose 4k over RT. - If you can run most settings at "high" (eg postprocessing, texture resolution, volumetric effects, water effects, etc) with RT on, but "ultra" with RT off; you're going to chose maxing out everything else over RT. In other words, it doesn't just need graphics cards capable of running RT in some form, it needs graphics cards capable of running RT at 4k with everything maxed out. And at the moment that means only the 4090, and there's very few people who want to drop over £2k on a graphics card (and fit the big bastard in their case and feed its power requirements).

[@hagidekuh]

Here is my opinion, I think ray tracing just outright looks better, but at the moment it has a long way to go (mainly in performance) before it would be worth it to actually enable in most games, I have a 3060 card and I mainly only enable it when I want to take pretty screenshots of things in games like Fortnite and Minecraft.

[@OctoFloofy]

I do play with highest settings in fortnite with Lumen etc enabled but i leave hardware raytracing disabled. The difference for me between software and hardware raytracing is almost not noticeable anymore.

[@Tech-is1xy]

@@OctoFloofy Lumen is still ray tracing. So you do agree with their point that ray tracing looks better

is it RTX though? or engine based raytracing through nanite?

its okay i guess. Played cp2077 with rt on psycho the first time. Second time i just used reshade and slapped some filters on, honsetly i liked the filters more

[@jacobgarcia4659]

In the tomb raider scene raytracing has more frames then rasterisation, i think you made a mistake 😅

[@Pazo139]

I don't like how raytracing has these gradual grainy effects when quick movements of objects and adjustment of light is made. I don't know if that just natural of it or because I'm not rocking a 4090. It takes up so much performance for hardly any visual gains. Maybe this just depends the game itself. This is easily noticeable in raytraced Minecraft Bedrock.

[@RocketPunches]

I think the end point of RT is just as another notch on the quality settings. Like, as an indie dev who works in unreal, I don't see a lot of people I know using RT for their projects. Lumen can be used without RT, and still produce great results. The RT just makes things like reflections more accurate, but Lumen does plenty of other things like allowing for emissive materials to cast light, and that doesn't require hardware RT, i.e. Nvidia or AMD path tracing solvers. Godot also has a novel, similar lighting system called SDFGI, or Signed Distance Field Global Illumination, which is also not hardware dependent. Similar to a point you make, rastering is already so good that in a lot of cases RT is just serving as the equivalent of a new notch on the shadow and reflection quality sliders. Right now RT is like Hairworks was back in the day. It's a marketing gimmick, where Nvidia can pump a lot of resources into partnering with a game to show off the tech to push their cards. It's not a reasonable solution, since it's pure brute force with a technique that just isn't suited for real time on consumer hardware to begin with, and as a result AMD and Nvidia are developing stuff to side step its hit. What I see as more likely than stuff like DLSS persisting as a necessary evil of RT, is simply engines getting better at just doing that work on their end (like with Lumen), so they don't have to worry about it. Because at the end of the day, the best solution for the devs in terms of accessibility is going to be making sure people have access to the stuff they show off at keynotes and stuff like the VGAs. Making the game equally performant for everything is significantly more desirable as a dev than relying on someone else to make sure you don't exist in a weird edge case where their stuff doesn't play nice with yours - a thing we've already seen a bunch of with DLSS and FSR. Beyond that, at some point Nvidia and AMD will wear out the top end of the market, and there will simply not be more people willing to upgrade if they have a 4090 or 5090 that's still running games well because the underlying tech has matured. Which is something I don't think they're really counting on with DLSS and FSR in the mix. If anyone cracks the code on a better method of efficiently faking GI even closer to RT, which I think is definitely within the realm of possibility, then there's a good chance that DLSS and FSR create some very nasty clashes between the companies and their consumers as support is dropped to try to maintain the high end. Either that or Nvidia and AMD eat a boatload of losses. And that's before you consider issues with how the AAA space operates as businesses in terms of their ability to sustain these massive Live services at the top of the industry and whether or not indies that already rely more on stylization or just designs that don't lean on fidelity even care at all about RT as a feature. My money is on the top falling off, the indies not caring (because I'm surrounded by them all day), and the ability of all the code wizards out there to negate their reliance on hardware.

[@frederikgoogel5611]

Software lumen still is rt. Hardware lumen is just more accurate and more expensive. Your statement that rt is not meant for realtime is simply wrong. Rasterization has its limits and we are right on its limit. There already are situations were rt is performing better and it scales way better. If you want to increase graphics quality, reasterization can only go so far.

[@pawnix4122]

If you only play games, ray tracing is pretty cool, but not necessary. If you work with graphics, such as making video games, offline/real-time rendering, and movies as such, ray tracing-capable cards is a MUST.

[@Whoareyoucalling]

Current implementation of ray tracing does look good especially when developers add the full suit not just shadows and ambient occlusion then slap the ray tracing label on most people have no clue what that is. Real time path tracing will be the show stopper in terms of visuals but it will take another 5-10 years before the performance impact is negligible so RTX 7090Ti and beyond is when I would expect to see path tracing be fully viable for ( reflections, refractions, shadows, ambient occlusion, Global illumination, ) That being said Probe based and cube map rasterized lighting, reflections and shadows are getting very good and in some cases look similar to todays ray traced counterparts.

[@frederikgoogel5611]

Cyberpunk is running 4k60 dlss without frame gen. A 5080 will run it easily. Rt performance is doubled per generation and i think that will continue for some time.

[@sporeolegy]

Unbelievable I got every one wrong 😂

[@sledgedragon2677]

Fortnite reflection raytracing is still very screen-spacey. You can still see the pickaxe reflecting in the water despite being closer to the camera. It's very strange that many "ray tracing" graphics modes only effect shadows and lighting but don't effect reflections at all, whereas some games only focus on reflections.

[@mrmatejator]

Dunno if I am the crazy one but the only comparison which I got correct was Fortnite one. I assumed that RTX ON in Tomb raider and Witcher was the other way around. The interesting thing is that I also compared which image looked better to me and in all 3 of those cases I preferred the side that turned out to be RTX OFF... Wild.

[@christianmartinez2179]

One HUGE advantage RT has over rasterization on reflections is obviously that RT does not depend on screen space so there's no weird missing reflections when the camera is not at a straight angle from the reflective surface, another advantage should be global illumination but Unreal developers also did an incredible job at emulating that with Lumen Note: I actually hate that nobody knows what RT is and they think is just fancy graphics with tons of filters on. Like all those content creators making "RTX ON" game remakes or literally just putting nvidia filters on top of genshin impact and calling it RTX or shit like that Edit: I almost forgot about colored shadows and soft shadows but nobody seems to utilize those with RTX

@@xXDeiviDXx I know it's been the main way of doing realtime rendering in games all that time, but knowing what's it used for doesn't mean I know what it is or how it works.

@@martineyles Because rasterization is simply reordering pixels to show an image or model on screen, it doesn't come with fancy effects like lighting or shadows so it has to be coded as a separate thing

[@barkoz]

How are there more fps in the raytraced Shadow of the Tomb Raider ?

[@KnightTheKnight]

Funny thing on the Witcher rasterized looks much more realistic; I explain why, better and comfortable for the eye compared to raytracing. why, because shadows are darker in real life. Shadows are so dark in real life that you can literally notice shadows on a grain of dust; no joke. the stronger the light the stronger the shadow, especially when the light is directly opposite than the shadow cast. shadows are stronger the closer the object is to another abject; when the shadow is cast at that opposite object, Thats why raytracing is complete idiocy, let me explain, on 5:21 look on the darkness of the murals on left where it says raytraced; you can see that even if the murals are casting an immense intense dark shadow, the murals are extremely bright; witch isn't how light works. matter affect, ray tracing is extremely dumb, and is incorrect on how it works. the sun creates light, and that light is thrown everywhere; that means that light isn't casting any form of beam; its a constant; as in its just a single mega giant beam of light what's casting beams is the shadows; in words shadow beams; light exclusively reflects when it hits an object with; literal reflective properties stronger reflection the more glossier. light exclusively turns into a casting beam when the source that creates it like laser, or the specularity of the surface it touches; glossy-reflective-non opaque. and the number of beams casted is fully dependent on how the item is, and how much faces it has; for example, disco ball has lots of faces causing lots of beams; in words beams are created depending on the reflective faces of the object, and the intensity of those light beams; varies; with how glossy or opague, each face is. also shadows are light; a complete misconception people have is that shadow isn't light, neither its case beams; that's wrong, shadows are actually proven to be a type of negative opposite light beam; PROOF; Shadows can reflect in mirrors; if shadows where not a beam it will be impossible to see it on a mirror. so no; Ray tracing is literally the biggest fallacy of the industry; not only its badly done; but how it's made to "reflect real life" is completely wrong because, from a fundamental standpoint. LIGHT IN REAL LIFE DOESENT WORK LIKE RAYTRACING. light sources don't throw a thousand beams; its throws a giant aoe consistent beam. Shadows also throw beams and are a type of negative light. Light exclusively reflects and varies depending on the object it hits, and its faces of reflection; changes amount of beam. Thats why almost everybody Raytracing is extremely ugly, that's why starfield npc faces are extremely ugly; because the lighting and shadows and how it works, is fundamentally wrong in raytracing, and many people have an erroneous information how light even works. ALSO even the reflection is wrong; reflection do NOT have the visual effect of raytracing; that is completely wrong; reflection works on the faces of an object, the more faces the more instances of exact reflection of the entire scene; that means if for example a disco ball where to reflect and have 20 reflexive sides; it will exactly reflect anything opposite to those sides. and each, side will reflect the exact same thing. basically, if you put an orange you'll see 20 instance of the oranges and what surrounds it on the disco ball; reflection works on faces; and reflective faces are like if you put a camera exactly on the middle of each face and press record; that's how reflection work. that means no, when light hits an object; it doesn't create multiple reflection and beams; it creates one giant aoe beam, and projects its image across anything with a glossy/no opaque surface in the POINT of VIEW of that glossy/reflective/non opaque/less opaque object. what happens, is that this surface collect all the light that is being thrown at it; and projects a single giant aoe beam that is proportional to all the light intensity from all objects that reflect its image to it; and the final image while Eual the same intensity of the reflective light all other object projected onto it modified by its opaqueness/glossy; glossier more intense/brighter, less glossy or more opaques less intense/brighter. In other word, its like reflection, is like the pov of a reflective object of all objects that throw light at it. it fundamentally works massively different than raytracing. In a room you can basically expect each object to project an image of itself at a certain light level depending on its opaqueness/glossiness/faces; and all objects absorb the image of any object that also reflects its light/ and shadow. so basically, it's like everything has a camera seeing other object, and the camera brightness, visibility of objects, etc depends on both the specularity and light reflective of every single object in the room, and the specularity and light absorbs and reflective of the individual object itself who projecting the image of all other object. IN SHORT basically, it's an endless loop of reflection, light absorbing and beam projection; and how light, shadow and reflection work in real life, is extremely different, and highly much more insane resource consumption that ray tracing; that essentially means realistically you would need computers even stronger that the best quantum computer in existence; to be able to run it. Raytracing, and game trying to look realistic, is a complete fallacy, a lie, and a toomfolery pursuit of simply something that just not realistically achievable even in million of years of technological improvement; in other words, people are being gaslighted and having the money taken from right under their noses, by anything that promoting raytracing. games are being made worse for no reason, and have fps issues for no reason; also mega lost of style, and technique/etc of graphical creation from games who use raytracing, Its a mega lost; the only reason why people would get a beefier pc; is so the game can have more complex mechanics, support more mechanics in them, and have a higher depth of graphic style, by being able to create more refractions, and smoother shadows light, etc and have mutch more thing in the game like events, ids etc running withount crashing; witch is basically pointless because it needs more work, and effort from the developers, and more cost for more thing obviously; and more complexisty; in words, it's a money grab pyramid scheme, so devs can do less effort in optimization, and fixes, and addressing leaks, and so the sellers of the technology, can gaslight you into making your older devices magically not compatible with newer technology. basically, you could say pay wall from accessing clear games that can run on your current pc with no problem. in other words, AGAIN the progress and technological advancement IS NOT BEING USED to be better, or to do more; ITS just being used for the wrong reason; for the millionth time. Why can't people just freaking co-operate and do things for actual real improvement and progress. The only thing great new technology bring, are to play highly complex games like/similar to cyberpunk with stable fps; witch actually is a super high complex game, that is made as a good game, rather than a Chash grab. Or to have bigger complex worlds in Minecraft, or to have more mods in video game; that the only benefit for upgrading your hardware; to do more; to have better simulation/emulation of Sofware's like blender, gimp, cad, etc etc basically, it's to use the resources for programs and mechanics, mods, or things like Redstone engineering or open worlds with more complexity. But if you're upgrading just because of feature walls, better graphics, or raytracing, or to play the absolute disingenuous shit fest triple A gaming become your basically having your money stolen from you. Basically, buy products for actual improvement rather than laziness of optimization, and bug fixing etc. from developer, and feature walls. Especially if its games as bad as the recent triple A industry, crap release of unfun, and badly made games; like starfield. Thous are my 2 scents.

[@qaasi95]

I think you swapped the raytraced vs rasterized for Tomb Raider. Raytracing should make shadows softer, not sharper, and it shouldn't increase performance.

[@Rationalific]

Except for Shadow of the Tomb Raider, I generally preferred the rasterized look over the raytraced look. For example, at 4:04, look at the trees, particularly the one in the middle in the background. You can see directional lighting hitting one side of the tree, and the other side is in shadow. The raytraced tree is just bland, and pretty much the same color all over. Contrast is also better with the rasterized version. For The Witcher 3 at 4:38, again, there are no real shadows. It looks like the castle has a burn mark on the RT version, whereas the regular rasterized version has a nice shadow. The main character appears to be glowing somewhat in RT, but the other had nice shadows and more contrast. Okay, it's cool and everything that a beam of light can bounce and light up an area in shadow, but that may not be good stylistically or artistically in many cases. Also, RT is not at the point where it actually mimics real life, so it's still a somewhat shallow replica. But then again, there are times when scenes in real life don't look at beautiful as scenes in artwork. Light, shadow, and contrast are good to have, and if they have to be placed manually, so be it.

I've never used raytracing in a game. Never seen the point. A small increase in image quality for significant performance penalty. I think raytracing matters a lot more for artists than gamers.
