I wold love to see a deep dive video explaining the difference between forward rendering and deferred rendering as it is something I never manages to understand really well
@Navhkrin

TLDR: Forward Rendering -> System processes entire logic for final pixel color directly. Deferred Rendering -> System generates bunch of information about pixel first and does a 2nd stage where final color is calculated. Deferred Rendering allows for more optimizations because you can avoid running logic for objects that are occluded etc. But "storing bunch of information" itself has a cost.

Forward rendering: you render the geometry as is, then loop through each light and add that light contribution to the image. This is how it works in real life, where each light ray from each light source stacks on top of each other to illuminate an object. The downside is that you need to run your shading code, per each pixel, per each light, thus making the computation progressively slower the more lights you add. Deferred Rendering: you render your scene into different images, grouped into something called the gbuffer. Each image contains some information for the scene (color, normals, depth, etc). Then, you take that gbuffer, and by combining those previously rendered images, you calculate the lighting in one pass as a "post process" (deferred) effect on the rendered images. It's a bit harder to explain how the actual lighting is performed from the gbuffer, since it's not how light really behave in real life. But since you are basically combining a bunch of pre rendered images to create the lighting, this scales much better the more light sources you add to the scene. It's a much more complex conversation than it can be summarised in a short comment, but I hope this helps

Actually in recent times(pretty much the last decade). We actually moved to something called Forward+ rendering. Where we directly render the fragment, but to surpass the performance limit of multiple lights/decals, we divide the screen space into frustum grid/clusters instead, each cell only calculating x amount of lights/decals. The main reason of this paradigm shift is to avoid the excessive memory usage stemming from deferred rendering numerous buffers needed for various effects, while recent hardware can easily calculate the clustering and culling. Though deferred rendering is not totally gotten rid of, it's still part of certain effects of the pipelines. So most recent (big budget) titles use the clustered forward+ with a touch of deferred.

​@@Navhkrin Deferred Rendering essentially stores a lot of information regarding lighting information (diffuse, normal, roughness, specularity) in something called a GBuffer, which as you say has the actual lighting/shading part calculated later in the frame. It can handle a large number of lights at once, while it becomes really demanding with higher resolutions and can even cause performance issues with multisampling. Forward Rendering has things drawn as they're queued with the lighting/shading process usually not done later. There's also techniques like Clustered Forward Renderering which attempt to fix the issue with multiple light sources, and that's what Godot and Unity uses. Interestingly enough, Doom 2016 and Eternal does use Clustered Forward Shading from what I've read. Source 2 uses forward rendering. If I recall correctly, even some of the Forza games use forward rendering as well. I do wonder how Doom Eternal is doing raytracing in a clustered forward rendering context.

Absolutely incredible video Alex, bravo! This answers so many questions I've had over the past few years regarding MSAA and TAA that it feels like you've read my mind. I've long been frustrated by MSAA options seemingly disappearing over the last decade and a half, and also remember you (or John?) mentioning off-handedly some time ago that "modern graphics just don't work without TAA"; I wanted to know _why_ that was the case but until now just treated it as a puzzling fact of life. Now I know it's because MSAA only affects geometry, and so cannot clean up edges within geometry introduced by stuff like transparency in textures (e.g. metal grates or fences) - and of course other stuff it can't help with, like pixel shaders, etc. As someone who primarily plays games on their PC with a 1080p/60Hz monitor, I also really appreciate your look into why TAA can be perceptually worse for my use case/setup than with others. All in all, an astonishingly comprehensive video without being overly long or laborious.

What he said about MSAA isn't quite right though. In a forward renderer, MSAA (FSAA to be more specific) was provided by the rendering pipeline itself at no extra programming effort. Whereas with a deferred renderer, you need to explicitly incorporate MSAA into every single shader. **Every. Single. Shader.** This means at minimum you need a completely separate set of shaders for no-AA, **every level** of MSAA you intend to support. That said, you can use a preprocessor to simplify the creation of the MSAA capable shaders. And to make this all worse, in a deferred renderer, you also need to use specific texture formats that support MSAA with the exact sample count you intend to use on it. Don't quote me on this, but I believe MSAA doesn't work if you don't do this, and blows up if you mix a MSAA shader with a non-MSAA texture and vice versa. These MSAA shaders don't "multiply geometry resolution" but rather run multiple samples per pixel to produce the final image. As an aside, because this is how it works in a deferred renderer, you can actually mix and match; running separate parts at different MSAA levels. Not that games do that (except in cases where they lack a MSAA capable shader) because it's easier to just generate a consistent MSAA block. All in all, that is the real reason MSAA died off with the advent of deferred rendering: It requires significant extra dev time to produce both MSAA (and per level) and non-MSAA variants of shaders, And wastes a lot of dev time when they have to hunt down bugs spawned from mismatching MSAA and non-MSAA parts of the pipeline.

Deferred rendering was actually first implemented in the _Shrek_ tie-in game, of all games, for the OG Xbox. I've read that the game's graphics programmer felt that they went all out with the visuals as they weren't constrained by having to develop the game with very low-end home computers as in the case of the kids' games they used to make. And then came _S.T.A.L.K.E.R._ by GSC which further popularised the technique, followed by _Grand Theft Auto IV_ which infamously shipped with a vaseline filter in lieu of a proper AA solution.

The environment is pretty similar to Crysis 1 in terms of lighting and requirements.

To address the issue of performance hit of supersampling, if you want a clear TAA image, then you have to go 4K, and you also have to do 120+ Hz. At that point, for people with 1080p 60Hz setups, I’d argue reaching those targets are more resource intensive with TAA than just plain supersampling at their native refresh rate So we ditched SSAA because of performance, but to clear up the mess that we made now with TAA we have to go high res and high refresh rate. Seems like we are back at square one. That’s why no AA option is important. For people who don’t want TAA’s negatives, the only escape is to take a performance hit regardless, unless there is TAA off option in the game.

As a member of reddit's "FuckTAA" community, I loved the video! I personally didn't know about how TAA is supposed to boost performance, I always taught it is bad for performance because it makes 1080p look like 720p and 1440p look like 1080p, so I actually need to render the game on much higher resolution compared to MSAA to get the same sharpness, wasting a lot of performance, it was a real problem on my old RX 470:) And even on my 3080 Ti it can be a real pain in some VR titles. But games like Assetto Corsa Competizione almost solves the TAA problem with offering low/high/medium TAA, so you can choose between more blurry or less blurry TAA, depending on your resolution and taste. I really agree with the future proofing idea, I think most games don't need any AA at all at native 4K resolution (I'm playing on a 48" TV from 1.5m). Except the problematic ones that "forget" to disable the sharpening that is there to make TAA less blurry, even if you turn off TAA, making even a 4K image very jaggy and flickery. Sadly too many games has this issue, you also mentioned it in one of the Resident Evil 2 remake videos.

The biggest revelation with TAA for me came from foliage and tree leaves and other transparencies, how it squashed the shimmering and flickering on that stuff in motion and brought so much stability to the final image. As more games started doing large open worlds with lots of details and flora, that stuff really became a nuisance since standard MSAA methods didn't touch that stuff at all, and FXAA basically didn't do anything but blur the screen a bit. TAA also blurred the scene, but helped so much with the aliasing on transparencies, and all you really needed to counter some blur and bring back finer detail was add some light post-sharpening. I think Fallout 4 was the first game that really sold me on it, but at the time I remember so many people hating the "vaseline smeared" screen blur and softness because there wasn't any built-in sharpening, and most people weren't on to using pp filter injectors like sweetfx or reshade or whatever was common at the time to help out with that stuff. Eventually most TAA methods included some forced or optional sharpening on a slider, but it was a slow process there. I wonder how the TAA in that game holds up in terms of ghosting and afterimages? I really don't remember seeing much of that stuff in Fallout 4 compared to later open world games where it was brutal like pretty much everything using UE4, and also one of the worst offenders I can remember, RDR2.

You're describing something that was kind of brushed over in this video, which is that sampling from previous frames doesn't just have the effect of reducing the spacial aliasing (due to camera jitter giving it more samples around the same pixel), it *also* has the effect of actually temporal anti-aliasing, as in it uses the *spacial* samples to reduce sampling errors in *time*. To me this is far more important than reducing edge stair-stepping effects, even at 1440p those are pretty hard to see outside of extreme cases like telephone cables against the sky.

The bad thing about TAA in most games is that it kills motion clarity if it is not implemented properly. And even the best implementations of TAA still will harm motion clarity, but it might not be super egregious at least. In other words it could make a 4k title look like a 1440p title whenever the game is in motion. I think that TAA is here to stay, which regardless of what I said is neither good nor bad. TAA implantation slowly but surely seems to have been improving over time. I'm hoping that as hardware improves TAA will be phased out and replaced with something better similar to how MSAA and FXAA are getting more and more rare.

Hi Alex! Excellent video! I wish you had asked me for comments though :) I think there is a brief way to summarize the core of what Temporal is: - I have to run 1000 instructions per pixel to look good - What if instead of running 1000 instructions; I ONLY RUN 250 AND ON THE NEXT FRAME I PICK UP FROM WHERE I LEFT OFF? - So we need to render at least 4 frames to get the final result - Problem is, if objects or camera are moving; the pixel "moved", so we can't pick it up - Solution to that is Motion Vectors, which try to guess where our pixel was last frame - If the guess is correct, we get a beautiful picture - If the guess is wrong, we get a blurry image (because we're picking up someone else's work and mixing it with our own) And that... is temporal. The quality of TAA boils down on how many frames we spread out the work and how good the guessing algorithms are; which boil down to the quality of the Motion Vectors. Motion Vectors are really hard to get right. For example an object moving is easy, but what about that object's shadow? What about materials with scrolling textures? If we forget adding MV to these, then they'll be blurry. And what about pixels that are now offscreen? And that's why it's called "Temporal". Because it spreads work over time. In a way, temporal is a form of cheating. But on the other, as you said, it would be impossible to achieve the quality we have arrived to without it.

Your post just made me realize something. The point of ray tracing is to be more accurate with lighting and reflections, and to reduce the amount of work-arounds or hacks that need to be done for accurate lighting. But then we have TAA, upscaling, and dithering tech doing the exact opposite by creating new hacks to make up for the ray tracing performance loss. We are just swapping some hacks for others. I preferred when I could choose for games to not be blurry.
@darksylinc
@darksylinc 7 ай бұрын
​ @Zyxlian Yes and no. What you said is true. However raytracing replaces tricks done in rasterization. Those tricks are often really far from how things work in real life, and break apart when used in other contexts (e.g. give more control of the camera to the user and suddenly reflections break spectacularly). But Temporal is just a hack to compensate for the lack of processing power. Which means in the future w/ more processing power you can just remove the temporal aspect and it will run with crisper quality. The same cannot be said of the rasterization tricks. Give it unlimited performance and those tricks will still break spectactulary given the wrong camera angles; as it is a fundamental problem w/ the trick. (personally I also prefer crisp over blurry 9 times out of 10. IMO Detroit Become Human comes to mind that pulled TAA off, but it is a slow-paced game, almost interactive movie-level, so it worked well there)

Have you seen the comparisons at 20:29? The more FPS you have, the less of an issue TAA becomes. For competitive games you probably want _all the fps._ Because it's important that you see the guy before the guy sees you. Even by a split millisecond. And preferably at a higher resolution, so you can identify the silhouette of the enemy at a distance better (instead of from 3-4 pixels). Which means you can't effectively use MSAA, which would cut the frame rate in half at higher res, so some kind of post-processing is better. In this case, TAA. FXAA and SMAA (not to be confused with MSAA) look okay as static images (screenshots). But in motion you're right back to jaggies. All AA options have drawbacks. Because of the inevitability of trying to render things that don't fit neatly into a pixel matrix (screen). So just pick the one you think looks better and forget it. Just enjoy the game. Some people get too hung up on these things.

The discussion around TAA makes me feel like I'm constantly being gaslit. I appreciate the lack of jaggies, but every image that was shown with TAA looks as though the entire image was rendered at the next resolution down. 4k renders look like 1080p, 1080 looks like 720. To me, this is simply not worth the tradeoff. The amount of money and hardware that goes into rendering 4k just to get the same clarity output that we had 15 years ago feels like the biggest scam in the industry. You mentioned the leaps in console generations, and I couldn't disagree more. I honestly don't feel like console games in totality look any better than they did on 360 and PS3. The latest Forza Motorsport being a good example. I don't even think it meets the visual quality of the previous games, let alone beats them. It just looks like they cranked the effects to their most unoptimized ultra settings, and compensated by dropping the resolution to 720p. Cyberpunk has all the pretties enabled, but has about as much detail as rendering it on a flip phone. This is also why I don't really stan DLSS. People say that it's better than native, but that's simply not true. Native without TAA always has noticeably more detail than even quality DLSS. The only reason it gets so much praise is largely because TAA is so bad. DLSS absolutely does help to alleviate some of the the detail loss and mostly keeps the anti-aliasing intact, but still can't compete with the inherently jagged output of pixel-perfect native. Regardless, I agree with your conclusion that we need options, and appreciate you taking the time to make the video!

The claim that DLSS is better than "native" is because native in almost all cases runs forced TAA. Native without TAA still retains more absolute detail, and DLSS only receives such high praise because its desperately working to claw back the detail crushed by TAA. Now, DLSS still retains most of the anti-aliasing work, and that definitely counts for something. However the end result is still lower absolute detail when compared to straight native without TAA, while both techniques still introduce temporal instability in the form of artifacting, as mentioned in the video. TAA solves edge shimmer while introducing other forms of instability, and the tradeoff is a significant downgrade in clarity. Many options are still the best solution, but I personally don't view the tradeoff as being even close to worth it.

Back in the 3dfx days the AA that the Voodoo 5 5500 card did looked amazing. It was a type of supersampling, but the way they did it was a bit different. Say you gamed in 800x600 and chose 4x AA. It did not render in 1600x1200 and downsample to arrive at the final 800x600 resolution. It rendered four different images at 800x600 with slightly jittered origins, and then averaged those four images to get the final image. This is one way of doing rotated grid supersampling. But for whatever reason, this was quite superior to how Nvidia and ATI/AMD do supersampling. To this day no AA methods they use came close to the results 3dfx got with their method. I got my 5500 when they first came out, and stayed with it until the GeForce 3 finally drew me away from it. The very first time I fired up a game I was disgusted with how bad the AA was in comparison the 3dfx card. But by then the performance penalty wasn’t acceptable, hence the move to the GF3. After living for years with the 3dfx’s superior AA it was painful to go without it, and to this day I cringe constantly at all the aliasing artifacts that I have to look at every day when gaming. I had hope when Nvidia bought 3dfx’s IP that they would eventually put their AA method to use in a GeForce card, but unfortunately that never happened. It would be so nice to have actual good AA again, but I doubt the day will ever come.

These horizontal lines popping in and out of existence seem to be dealt with rather well in the TAA shots, but for whatever reason these types of artifacts are horribly prevalent with MSAA and even SSAA methods, when they should not be. 3dfx’s method did away with those kinds of artifacts wonderfully. But you still see tons of polygon popping with horizontal and vertical stuff with today’s cards and MSAA/SSAA for whatever reason. It sucks. It is so annoying.

Youre looking at the aliased past through nostalgia tinted glasses. Ironically, most TAA solutions do exactly what you describe with jittering, but more efficiently. Supersampling isn't really "AA" in this context, because if you have the horsepower to supersample you could be pushing the actual quality of the rending harder. Pixel quality > pixel quantity.

It's frustrating that as you describe visual fidelity in modern games to have moved from being driven by geometric detail to texture and shading detail, that we have moved towards anti-aliasing techniques that sacrifice a lot of this new detail in the name of image stability. The impact of resolution on TAA's quality is a massively important point, and my anecdotal experience aligns quite closely with your findings. I had always preferred MSAA/SSAA where possible, and was frustrated by their absence or infeasibility in modern deferred-rendered games, but my 'breaking point' for frustration with TAA was trying to play Battlefield V on a 1080p monitor. Aliasing was definitely reduced by TAA, and image stability in specular highlights and foliage was greatly improved, but at the cost of making the overall resolve so blurry as to be essentially unplayable; enemies at distances greater than 50m or so would simply melt into the environment, and the per-frame (if that's the right word?) resolution of undersampled and accumulated lighting and volumetric effects made attempts to disable TAA via .ini tweaks result in a crunchy checkerboarded mess. The only thing that made the experience tolerable was an upgrade to a 1440p monitor and a 7900XT which raised both the frame rate and resolution to the point that detail that would previously have been discarded or homogenised was once again intelligible. Maybe the way to approach performance and image quality analysis in newer games might be some new metric of combined spatiotemporal resolution (or something, I'm not Geordi La Forge).

This was really informative, great work. This explains really well why TAA became the de-facto standard for antialiasing, how older methods managed AA, and why some people are more bothered by it than others. I think the best way forward from here would be an option to increase the render resolution of things that would be rendered at lower resolutions to be smoothed out by TAA, like Jesse's hair in Control. That way, you can turn TAA off for more clarity and just increase resolution on things that would normally be undersampled to make a better image, albeit at the cost of more render costs.

I hate shimmering and flickering with a passion, so when TAA was introduced I could definitely appreciate its positives; those definitely outweighed the negatives for me, even because thanks to shader injection I could mitigate the negatives with combinations of sharpeners et cetera. Before we got TAA as we know it today, I was always very excited to use stuff like TXAA or SMAA T2X when they showed up in the options, unfortunately it was a very rare occurrence, and I never understood why. I guess that's the same reason why they didn't show up in this video as well haha. I'd be really curious to see how those stack up vs today's TAA. Talking about the negatives, something I don't get is why post process sharpening methodologies haven't improved that much to go together and try to mitigate TAA's shortcomings. Sure, that would still not bring back details that get de facto erased at times, but it would surely help in the bigger picture. I am sure DLSS already does something internally in that regard, but then the sharpener that gets put on top, usually controllable by the user in the options, is absolute dogshit. An head scratcher. Nowadays I am a big fan of DLDSR and every GPU I'll buy in the future will take DLDSR into account. Once you try it you can't just go back. In any case, this was a great video and I am happy to see Alex bringing back this type of content. More of this pls!

SSAA is technically not "dead". Many modern offer a "Render Resolution" option that goes up to "200%" or "2.0". Pushing your Render Resolution past 100% is just "SSAA". You can also do this by just manually switching your game resolution to one that's higher than your default resolution. In my opinion, combining this "SSAA" and DLSS Quality still provides the best AA possible today bar none. The second best option is DLDSR + DLSS Quality

When TAA became more popular, it felt like 4K became what 1080p used to look like with sharper aliasing, to where even 4K with TAA just feels too blurry to me now. I hope a shift happens to where sharping aliasing is looked to be developed in the future, because it feels like we've been sitting at TAA aliasing for a while now. It goes even deeper though than aliasing solutions, renderers as a whole since a lot of games and engines switched to a deferred renderer focus, just typically look (to me) more muddy, though that's not to say some forward renderer game examples haven't also got more 'blurry' in this way too IMO.

This is a really awesome video, these tech focus videos are great overviews of complex graphics topics. I really do agree that there needs to be better alternatives for people that get motion sick or otherwise object to TAA, or at least mitigate of its worst artifacts. That is a big challenge though, modern rendering requiring TAA to not look noisy is even worse problem than really discussed in the video, depending on the techniques used the image might not even be legible without TAA. According to the devs of Dreams in a 2015 SIGGRAPH talk a frame of that game before TAA is basically white noise.
