DLSS 3.5 - Better Pathtracing for Free

This video is a paid promotion for Nvidia. In it, I investigate Ray Reconstruction - which is DLSS 3.5's trick to preserve more information from path-traced scenes.

[@ipodge1731]

I think Alan Wake 2 was made with ray tracing in mind because of how big the role of light and shadow is to the game's theme. Maybe you can check that out? It also uses DLSS 3.5 with ray reconstruction and everything.

[@cyandrix]

If it helps, at least you know AMD will keep providing your aging hardware with fresh coats of paint, like with AMD's FSR. Nvidia ditching hardware older than their previous generation is whats going to keep me from using them in the future. Not everybody buys a new GPU every two years, Nvidea...

[@MrBrax]

And not only that, but amd tech works on nvidia gpus

[@bulutcagdas1071]

It's fine, only the 4090 or the 3090/4080 can really do this stuff anyway. At lower resolutions, ray tracing is really annoying with garbled artifacts. It's really going to take until the PS6 era of consoles where the mainstream GPU's can handle these workloads that it'll be standardized. So as it stands, its a nice little gimmick for 4090 owners. Not very representative of the remaining 95% of the user-base.

[@Sevastous]

Thats what nvidia wants you to think. FOMO as marketing. I am on my 3060 with dlss2 and let me tell you. I don't use it at all. only game I felt I needed Upscaling was Starfield. and boy FSR in that game implemented brilliantly. no artifacts at 1080p!

[@SweetFlexZ]

Always with the same, waiting for AMD to catch up and release their worse version of something that Nvidia released one or two years before... AMD has to develop their tech and try to compete, but with this mediocre mentality they will never compete, numbers speak for themselves.

[@DeSinc]

small correction on 11:35, DLSS 3.5 does not always include all the parts, and older 20 and 30 series cards can run DLSS 3.5 with no access to frame generation. DLSS 3.5 refers as you said to the newest toolkit of DLSS options, including the new ray reconstruction all on 20 and 30 series GPUs, but only 40 series can turn on frame generation.

DLSS 3.5 is a version of the dlss suite that includes all the dlss features, so there's a 3.5 version of the upscaling, a 3.5 version of the FG, and RR was introduced in 3.5. Some cards can't use all these features, but they're still using DLSS 3.5 even if they're just using the upscaling. It's Nvidia's fault that they made it so confusing by conflating the version numbers with the features.

[@TerraWare]

@@x0Fang0x Right, they do

[@RicochetForce]

Yeah, Alan Wake 2 is not just using pathtracing. Even with 'RT Off" it's still using a software based path tracing model along with mesh shaders (primiitives) so it's always pretty heavy (especially for GPUs that don't support mesh shaders). That said, this is an Apples to Oranges comparison. Cyberpunk is a much faster paced game with far more active and demanding gameplay scenes than anything in Alan Wake 2. It's also an open world game with much longer draw distances.

@@Grandmaster-Kushthe tech will never be refined for normal people. The 2060 super, 3060 and 4060 all perform the same. Nvidia has a hard performance target for what customers will receive for $300, and it’ll never be good enough to path trace. And if the 4060ti and 3060ti being the same thing is indicative of a trend, by the time path tracing is accessible only 80 class gpus will be able to do anyways, at probably a $2000 cost, as the lower end gpus will be stuck at a specific performance target.

[@allxtend4005]

Photorealistic games ? sorry but RayTracing is bullshit and it is kinda stupid if lightning and reflection cost you 200% of your normal Performance. Photorealistic can be done already and without RayTracing, the best will be if AMD and Nvidia and Intel will go the RayTracing card as extra and not implement it in to the GPU. So gpu's will be WAY cheaper and people can chose if they want to be the beta testers for this tech 20 or 30 years too late because RayTracing is a old tech in reality.

[@i_like_Peanuts]

Companies are not going to let go of 1080p anytime soon.. They are going to keep handicapping performance on **60 series/AMD equivalent cards to make them a '1080p beast' but not anything special for 1440p because it would be quite a loss for them as cheaper cards providing adequate performance at higher resolutions will drastically take away sales from higher end/priced cards.. So regardless, The 5060 will still be marketed for 1080p gaming/workloads whereas it should be able to run 1440p easily.. Edit : I absolutely want this to age badly and be proven wrong..

[@evolvedSpoiler34]

Pathtracing without denoiser is pretty much how I see irl, except it's less noticeable. Just like pathtracing, it becomes more obvious in dark. People with visual snow syndrome would understand exactly what I mean.

[@realflow100]

Wow that sounds infuriating. I can't see any visual snow no matter how hard I try to look for or notice it even in the most extreme cases. its almost completely imperceptible even when I wake up in the middle of the night in a pitch dark room and try to look out at the night sky and stars at night. and after just a minute i can't notice even the most miniscule insignificant amount of "visual snow" at all anymore. It just looks like black hole void of nothing when i close my eyes in a dark room

[@Scorch052]

I appreciate that you took the time to point out that while the path tracing and ray tracing methods available can certainly look superior, they may obstruct the thematic tone or style artists are trying to convey, as I think that's going to be a difficult line for devs to walk until everything is completely compatible with that tech.

RTX branding is 5 years old now and it feels like there's only one desktop graphics card which is even remotely close to making the technology worth the development time.

[@Shopwood100]

The more technical videos I see of pathtracing/ raytracing, the more impressive I find old-style rasterization. I appreciate it takes a significant amount of time for developers to create scenes with the correct lighting, and that raytracing offers the possibility of more rapidly creating a realistically lit environment, but in so many of these comparisons I really don't find raytracing to look very much better than rasterized graphics.

DLSS has had a very interesting development history. Aside from gpu politics, Nvidia engineers are really doing something great here. The Finals has been a great ray tracing experience with RTGI, and it also performs incredibly well. RTGI really does impress in that game with how dynamic everything is, now the lighting can play catch up. No awkward color switching when objects are destroyed, everything is consistent, which makes the action on screen more believable and more immersive. It's almost how I felt when playing Portal RTX or Cyberpunk with PT, tho those two titles impress for doing something never done before.

[@Creepernom]

What is the solution, though? This tech relies on Nvidia's own unique hardware. Is Nvidia supposed to stop innovation just to wait for the others to catch up? I don't really see any way to solve this issue. Games are already getting designed around RT, for example The Finals.

[@odysseas4os]

@@Creepernom What a bluepilled sheeple take, was PhysX innovation that relied on Nvidia's own unique hardware? No, yet only Nvidia could run it, Why? because it was proprietary closed source software. This very channel has a video named "Nvidia, stop being a DICK" that's very relevant here, but i guess being a dick is fine if the tech is impressive enough. I'm sitting here trying to think what i could say to get through to you but i honestly don't know. Innovation doesn't have to be exclusive, computers are a platform built on open standards that everyone can use and improve, Nvidia should not be allowed to choose and set standards for the industry by itself (especially if said "standards" are proprietary). Look at Chrome, because its what everyone uses Google gets to decide what standards *exist* unilaterally. Recently google snubbed the JPEG XL format in favor of its own AVIF format even though JXL is objectively superior at what it does in nearly every measurable way and offers unique features that are better suited to an image format. Ultimately Google's motivations behind the decision don't matter, its not up to debate, Google just gets to decide because they have a monopoly. The fact that every other corporation that cared disagreed with them is irrelevant, if Google doesn't support it, it doesn't get to exist. Can you imagine if Nvidia could just decide that Vulcan doesn't get to exist by just deciding to not support it? or maybe some innovative Unreal 5 feature that in any way competed with one of their own features just doesn't get to exist? Now you might say what does this have to do with Ray Reconstruction? it has to do with it being part of a Monopolistic ecosystem that locks people in. If the content people want looks best only within the ecosystem people go in and once enough people are in they can start to take increasingly brazen anti-consumer decisions because there is no real alternative.

To the second guy i don't really understand what argument you're trying to make, i'm not arguing that ray-tracing is bad and shouldn't be used because AMD runs it worse, i'm arguing that locking it down with proprietary implementations is bad for the industry. Having three versions of every feature that are just different enough to not be IP infringement and all preform and look different isn't good for anyone and developers just like with PhysX are simply going to use the options available to everyone like Lumen by default which isn't even hardware accelerated and preforms worse for it, and then have a toggle for every vendor that pays them, to which i imagine your opinion is "Thank god hardware acceleration isn't standard across vendors, then i wouldn't be able to justify my parasocial attachment to a multi-trillion dollar company to myself".

But now knowing of all these issues makes me want to try ray tracing even less because with DLSS 3.5 you're foreced to upscale which comes with it's own issues and artifacts. I feel just normal rasterization without any upscaling is still superior, even if the lighting looks a bit worse.

[@lamarmottedesinternets5134]

It's called DLSS 3.5 because it's a chronological addition to the "dlss package" that way, games can display their "dlss version" to players, and we instantly understand what set of features are supported out of the "package"

[@_gamma.]

Wow, this is actually really cool. The foliage under those lights is amazing!

[@pingeee]

this is actually huge, maybe now raytracing/pathtracing can actually become viable

[@BigSoak]

Because it is called 3.5, i thought nvidia just didnt care about older rtx cards, but im really happy that this improvement inn all raytracing is coming to all cards

[@stargirl5194]

Amazing Thanks for the video 🤗

[@DarkAndromeda31]

what program is being used to zoom images together / swipe between them?

[@agentorange2618]

not sure but it might be Nvidia ICAT

[@jonathonschott]

@2kilksphilip, i remember the launch of the 20 series and i was under the impression that the inclusion of the tensor cores was for the purpose of de-noising and that dlss upscaling was an added bonus, but you seem to imply that this is the first use of the tensor cores for denoising as opposed to just an upgrade to the algorithm......... Im confused.........?

[@jonathonschott]

@@2kliksphilip so I went back and looked, Nvidia only stated they were still working on ai denoising when turning was announced, that was my confusion, I seem to remember them making a bigger deal about it than I could find. This whole time I've thought that's what their intended purpose was and that dlss was just an added bonus because they were already there, if the cuda cores are having to do both raster and denoise that would certainly explain the additional burden of 'rtx on' on turning, among others obviously. Thank you for your response, I recently found you and will definitely stick around, any content creator who inspires me to assign myself homework is certainly worth their weight in salt, and you play counterstrike, a game I started on around 1.4/1.5, so you also have good taste

[@combat.wombat]

I understand why you didn't do it here but a comparison to AMD denoising would be great in another video.

[@roamn4979]

AMD's denoising should look the same as pathtracing with RR off, since they haven't yet released their own denoiser and the alternative is using the game's denoiser which is used in all the ray traced frames without RR.

[@nelrick]

Is this a new setting that just came out DLSS 3.5? Or has this come out already?

[@Jack2421992]

7:16 is actually SSR (Screen Space Reflection) I always hated it. In many FPS games suffer from unbelievable reflections of your gun in the open seas. And when you tilt to a certain angle, reflections/shadows somehow stopped showing.

[@nixel1324]

I agree, personally I often prefer _no_ reflections over SSR. I've gone as far as to install mods to disable SSR for some games.

[@Chasm9]

What they've accomplished in Alan Wake 2 is incredible. RR there produces much more visually coherent image, to the point that I don't even feel like I'm using DLSS. In Cyberpunk it's not the case. However, I haven't tried the latest patch, maybe they've improved it.

[@cluckendip]

Have you ever considered working with Digital Foundry?

[@krich451]

Fizzing is a really good word to describe that.

[@Solano1111]

aaaa nice ad for nvidia, i already wanted to buy a 4070 but now i was remembered of it.

[@verebellus]

The non digital sharpness of nonrt mixed with the lighting of rt would be perfect

[@b4ttlemast0r]

Ray reconstruction and frame generation is nice to have, but the main Nvidia advantage is still just the image quality of the upscaling itself. AMD really needs to match NV's upscaling quality asap, especially cause the consoles also rely on FSR.

[@WaitNoIdidntMean]

I think it would be really cool if the source 2 workshop tools had a ray traced renderer for screenshots or animations, i think they do have something like that in cs2, but only for hammer iirc. What would actually be even cooler, if cs2 had a ray tracing feature for in game graphics, but i guess it would interfere with gameplay a million ways so i guess thats impossible

[@CronusTheGreat]

whats the best way to setup dlss on games like warzone?

[@LatteLobster]

After getting a quarter of the way into this video, I realized this isn't the sort of thing you can watch at 480p.

[@OutOfNameIdeas2]

Can't wait to use this in 1 of the 1000+ games I own

[@jeremyjohnson7676]

Which games are supporting DLSS 3.5? A list would be helpful!

[@_Devil]

Something I never understood is despite DLSS being an ai-powered frame generator, older RTX cards cant use new DLSS versions. Isnt it all the same generator, just upgraded? And if it's truly "free frames" that don't strain the GPU then why shouldn't someone be allowed to use DLSS 3.5 on their 2080 for example?

[@roamn4979]

All RTX cards can you new DLSS versions they just can't use the frame gen part of it. The reason for that per nVidia is that the old cards lack the additional optical flow accelerators which are used to calculate where stuff is moving on screen. Old cards have these too but the newer ones have units of these accelerators dedicated only for frame gen. However you have to keep in mind that that is from nVidia and could be just PR talk to safe face.

[@ironicdivinemandatestan4262]

​​​@@roamn4979People have tried running Frame Generation on 30-series cards (since they have a Gen 1 OFA, but not the Gen 2 OFA that the 40-series cards use), and it's a complete mess. The optical flow acceleration on previous cards just isn't advanced enough. You really do need a 40-series card for Frame Generation to work.
