[@delaorden]

@@FuZZbaLLbee most emulators use the CPU to emulate the graphics, at least the best ones. You would need an emulator that does a translation layer to a normal api (like the switch emulator with yuzu that calls nvidia apis) and apply a dlss reshade that doesn't exist yet as far as I know. So it's totally possible, but it doesn't makes sense for that generation of gaming plus developers need Nvidia permission to use the API. That being said, you could run the emulator from a pc and with gamestream remote play to a shield TV 2019 and use the dlss game upscale option. I really don't think it will work better than SMAA from most of those emulator but there is only one way to know.

[@TheLingo56]

Ironically not that hard to run these days and uses older AA tech :p Although funnily enough there's still parts that dip to 30-40 frames even today just because Crytek was betting on single core CPU performance getting faster than it did. Instead CPUs shifted to multi-core designs and Crysis 1's engine isn't well suited to that. Those sections also got stripped out of the console releases of Crysis 1 for similar reasons.

[@cyberdrace]

​@The Monarch I agree overall, however I would point out that some modern games feature equally or more advanced graphics and physics, however the difference is that they fail to incorporate any of this into the actual gameplay experience. For example the way destruction physics and object collison is handled is regularly on par or beyond what Crysis did many years ago, but you don't really notice it or are compelled by it because the game designers don't want to design core gameplay mechanics around the fact that the environmentis is accurately simulated and largely destructable, so they just choose to mostly disable it except for cosmetic purposes. What Crysis did exceptionally well was how it translated all the amazing technical advances of the engine into actual gameplay. It mattered that the physics were great because in addition of being able to literally blow stuff apart with grenades you also had a nanosuit that gave you super strength, allowing you to punch almost any object into orbit (well... at lest if you increased your strength value a bit with the ingame console), giving you a real sense of freedom and empowerment as a player, because you were allowed to realisticly engage these virtual environments on your own terms and with your own methods, in a way that didn't make you feel boxed into a specific, predetermined approach the developers wanted you to take. It mattered that vast amounts of foilage and terrain could be rendered in great detail with high draw distance and realistic lighting, because that's what it takes to recreate the experience of stealthily hunting your prey through a dense jungle like you're the Predator from Predator. Developers always talk about immersion as though it is achieved by graphics and other technicalities alone, however what matters most in my opinion is making the player feel like the choices they make are ones they came up with themselves, instead of having to pick them out of a small, arbitrarily constrained set of predetermined paths. Crysis was the perfect techdemo/sandbox/game-hybrid.

Another great video from this channel. Regarding his answer of whether or not DLSS "works" or not (he said sometimes it does and sometimes it doesn't or something like that). To be more specific, it works incredibly well for still shots and low movement, and the faster the camera moves the less effective it becomes. So it's pretty nice to have in general. You will only catch the uglyness after a quick head spin but then quickly it all melts away back to nice and beautiful.

Another way to explain this: When super-sampling, the value for a 'created' pixel will always be an interpolation of the pixel it was created from and its surroundings (i.e. a gradient). What DLSS does, is take a machine-learning algorithm, and apply that to figure out the formula for the gradient for a pixel based on what is happening on the screen. The network is supposed to figure out what hard & soft edges are in a frame, so pixels can be interpolated without creating aliasing issues.

I remember the day I upgraded from my Verite Rendition v2200 OpenGL card to my first 3DFX Voodoo 2 12mb in the summer of 1998 (or maybe it was 1999) being so impressed by 1024×768 with no Anti-Aliasing at >30FPS and 1280×1024 at 20FPS that I thought the whole Anti-Aliasing debate was dead in the water, despite liking it at 320×240 but my framerate being too slow at 640×480 previously on the Verite. I was playing Quake Quake2 ZDoom, Half Life and Unreal at the time.

[@Cimlite]

You still might want to use DLSS, even if you can run the game just fine, simply because it does a better job at anti-aliasing than other methods. It also happens way more than 60 fps, modern gaming monitors go as high as 360hz, and these upscaling methods have to be able to keep up with that.

[@emilemil1]

What I'd like to see is partial super-sampling. What if in an FPS for example we could render the center of the screen at true 4K, an outer perimeter at upscaled 1080p, and maybe the very edges/corners at upscaled 720p. That would make a lot of sense since it matches how our own eyes work, we mostly care about motion at the edges of our vision, and we can only focus on things we're looking directly at.

[@XSpImmaLion]

Crazy stuff... I kinda thought real time ray tracing was supposed to eliminate some of that stuff, but apparently not. Another great video guys, thanks!

[@Sekusamu]

I see the influence of marketing on the choice of terminology. At first I was skeptical that a 4K screen would have only 4 times the number of pixels as a 1080p screen. This is not a naive guess. I worked for two decades in image processing and our cutting edge film recorders in 1990 were billed as 4k, because they were 4096 pixels wide. 4K screens are, indeed just 4 times the number of pixels as 1080p. This is for two reasons. Firstly, because 1080p is named after the vertical dimension, where the horizontal dimension is 1920. Secondly, the horizontal dimension of 4K is only 3840 pixels. So, if they had continued the naming convention, 4K would be 2160p, and 4K has just twice the dimensions each way as 1080p, but doesn't 4K sound so much more impressive a jump up from 1080p?

[@ouroboros0311]

You are correct... 1920x1080=2073600 2073600x4=8294400 3840x2160=8294400

[@tuxedo_productions]

Spent quite a bit of time at 9:19 trying to find the difference, only to remember I'm sitting here learning about upscaling 1080p to 4k with anti-alias on my 768p monitor.

[@Robert-Wip]

First six minutes felt like an endless loop describing the same problem four or five times over again. Made me feel like it’s 4K instead of 1080p 😜

[@AlejandroLZuvic]

Exactly, I love Computerphile videos but this one was 7 minutes of just setting up the problem 5 times with the same words, and then the explanation is ok, but not really deep.

[@aitchpea6011]

Interesting note. I initially thought 4K was 16 times bigger than 1080p, thinking it was four times bigger vertically and horizontally. Turns out I was wrong. 4K refers to the horizontal resolution, whereas 1080p refers to the vertical resolution. They changed naming conventions to make it seem like you're getting more improvement in resolution than you actually are.

[@0x6e95]

4K sounds way more marketable. It's much better than saying the alternative.

[@joshuascholar3220]

He's talking about the network doing both morphic antialiasing and supersampling at the same time. While that would be a big improvement in speed, the gains we're seeing so far are so small that I think nvidia isn't even attempting the antialiasing part and they're taking an already anti-aliased image as the input.

[@guruprashanthrao1093]

[@florapeng3356]

Being a MLE, I'm learning variational auto-encoder myself, fascinating how AE can compress so much info into just a couple latent variables. Think VAE and GAN are catching all the attention with the ability to re-create real-like data(image, video, text) :) nice talk Mike.

[@brurpo]

It would be great to see a new video about it, how nvidia generalized the network so you dont have to train for a specific game, with much better quality, basically only needing a motion vector pass.

[@SyntaxDaemon]

DLSS 2.0+ is made of two primary components. The "AI" upscaling as talked about in this video is the second, while the first is just a temporal upscaling ("supersampling") method similar to TAA, and it's that first part which does that vast majority of the beneficial work. The "AI" component helps the apparent speed of the temporal resolve but doesn't really add much detail. For this reason, depending on the implementation, the developers may also choose to include an additional sharpening pass. Speaking of sharpening passes... AMD / ATI currently doesn't have anything which competes with this at all. The FidelityFX upscaling is just their Contrast-Adaptive Sharping (CAS) made resolution-independent with a basic upscaler (Bicubic or similar), and CAS itself is just an enhanced Lumasharpen. While certainly a useful and flexible way of improving the apparent fidelity of the image, it does not compete with the temporal sampling solution seen in DLSS. There's a whole conversation to be had on how games are made and optimized, and how Nvidia is pushing the technology of the market in their favor.

@Computerphile Dunno if it was pointed out before but he misspoke at 0:28: he said "run it at a lower frame rate" but actually means "run it at a lower resolution".

[@veggiet2009]

I think the nice thing about doing something like this on a game is that the network can be trained not only on "games" in general but they can be trained on the particular game that they are expected to work with. And I think also it could take advantage of other parameters that a game can offer that, say, a tv show can't. For instance you could theoretically get your 1080p aliased render to also render a 4th channel in addition to the RGB, maybe the 4th channel is a rendered wire frame or maybe it's depth or maybe it's a value that represents a particular quality that the object has, then you train the network on that 4 vector data... I would imagine the output would be significantly higher quality with access to more data that a game can provide.

[@jackbrabham]

Great video, never quite understood anti-aliasing techniques until this.

[@_NaLo_]

5:20 Correction: Multi Sample Anti-aliasing (MSAA) does use multiple samples per pixel but ONLY for pixels which have an edge going through them, so pixels in the middle of a polygon aren't affected. It is highly unlikely that all pixels have edges running through them. Full Screen Anti-aliasing(FSAA), aka Super Sampling Anti-aliasing (SSAA) aka render scale, does it for ALL pixels on the screen like he describes however.

[@pottuvoi2]

Slight correction. Multisampling calculates shader/texture once per pixel and stores result to all subsamples in pixel which are occluded by the polygon. Color, Z/Stencil buffers have all subsamples and every one is updated each time pixel is written. This is reason why only edges are affected and it still handles cases like intersecting polygons correctly. If MSAA would only affect edges of the pixel it wouldn't handle intersecting polygons correctly. (Like the 16xAA Parhelia used.)

Speaking of Computerphile and games, where the heck is Miegakure? I'm dying and I'm worried I won't get a chance to play it; I only have a few decades left. Please do an update video to pressure him to finish it.

[@HMan2828]

A few additional points to mention... DLSS competes with other things that use the tensor cores only, like real time ray-tracing, in terms of performance cost. It doesn't impact the normal (non-RTX) load on the card by the game, unless the card's thermal solution is unable to keep up with regular cores, CUDA cores, and tensor cores all being loaded, which would cause thermal throttling. If you lower render resolution to 1080p and DLSS to 4K, without ray-tracing, you get the full performance benefit of lower render resolution, with no performance cost from DLSS (apart from the static frame time). If you use ray tracing and DLSS, then DLSS only impacts the performance of the ray tracing features. Also worth mentioning how other technologies like GSync frame doubling also improve the framerate on top of all of this.

[@Chloe-ju7jp]

I wonder if the thing he misspoke about could also be a potential solution. He accidentally said "lower framerate" instead of "lower resolution", but now I'm wondering if you could run at a lower framerate and just ai interpolate frames

[@xTheUnderscorex]

It occurs to me that there's no reason that, if you're rendering this way, the NN input has to look anything like a fully rendered 4k bitmap with exactly 3 colour channels and nothing else, it only has to be able to provide the information needed to produce one. It can be whatever combination of layers you want at whatever resolutions you want, with all sorts of possibilities for what they could be. Say you calculate: a 1 ray/pixel raytrace layer at 1/2 resolution; an unlit rasterized layer at the target resolution for detailed texture info; and maybe some kind of edgefinding and z-buffer layers at 2-4x target resolution. Whatever is found to work best as a tradeoff.

I think it would be best to have DLSS settings for a short list of general visual styles, and then each game will just tell the card the appropriate one. Like have cartoon and photorealistic options, so it knows whether to make things smooth gradients with sharp edges, or noisy an detailed (and if video compression for say Netflix could also get those two options, that would be great). When you zoom in to the level of dozens of pixels, there aren't really that many major ways to vary how a game looks. The DLSS might be able to figure out the appropriate action itself, but it would probably run faster if it had two or maybe a few modes, so had to think less about context for each operation.

[@jpvillaseca]

Fantastic content today! Thank you for the thorough explanations

[@minmaijd]

I'm curious to know what they are training the network with specifically. It sounds like pixel data, but I can't imagine, even game specific, how a neural net could upsample. The variation in frame composition seems like you would get a lot of artifacts or noisy behaviors. The network doesn't presumably know if you are looking at a car burning or an open sky, for instance, which wouldn't remotely upsample the same.

thing is with 4k and a high enough pixel density (like on a 27 inch monitor) you barely notice jaggies, if at all, so running AA only serves to blur the image, unless you're getting weird shimmering jaggies it's probably not worth using at that point.

Two of the best examples of DLSS are Rise of the Tomb Raider and Shadow of the Tomb Raider. I have never seen DLSS in such a good condition.

DLSS 2.0: “Yo wassup”

@@soraaoixxthebluesky I was just about to post it. Things have changed big time.

This misses the most important part: DLSS is a form of TAA. The pixels are not from just this frame. They are from the previous frames too.

[@TheWalrus19]

That started with DLSS 2.0, which came out after this video. DLSS 1.0 is very different. Maybe time for a follow-up video?

This is like watching a very intellectual version of The Office. Love it.

Thanks for the explanation. It was bugging me on where the training data came from and how it can be applied so generally. It seems the answer is fairly obvious: do the work before release.

[@ytubeanon]

I wonder, if there are many possible scenarios in a game, like in an open-world game, does the AI move a virtual camera along every possible path a player can take as part of its training set

DLSS is extremely useful for raytracing because of the considerable fixed per-pixel cost, while high-end GPUs are fillrate beasts, and screen resolution has negligible impact (depending on complexity of lighting & texture effects of course). Cyberpunk 2077 with ultra raytracing on is jaw-dropping but it seems like they could compromise a bit by doing a separate low-res raytrace-only pass and then blend that in rather than doing whole image upsampling. Just pondering.
