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.

​@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.

This is not only topical, but also incredibly interesting. There is a lot of talk about DLSS these days, but very few explanations on how it's done. Now that you have brought it up, I'd love to hear more about antialiasing techniques in 3D applications. These have advanced by leaps and bounds in the past years, especially with the introduction of temporal AA.

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.

I was playing Quake Quake2 ZDoom, Half Life and Unreal at the time.

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 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?

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.

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.

I'm assuming antialiasing is being done on the entire image. I'm wondering if they could do some sort of edge detection algorithm and then only do antialiasing on the area where edges are detected? You could potentially have a quality setting for it much like edge detection filter effects where if you turn the quality up, it detects more edges.

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.

Do you think of testing and training a model in order to get higher resolution image from low-res image or the same resolution image looking just the same with super sampled image?

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.

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.

Now what if you have dynamic resolution and use DLSS to clean up those lower resolution frames. How fast/often can RTX cards choose whether to use DLSS for frame or not?

Maybe I should read the paper behind, but here is a simple question. Do the plan to train different models for say different levels? If you're in a bright field or in a dark cave, that makes difference even in the same game... They could as well use the same model for several games that have similar levels.

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.

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.)

At 13:05, what is half resolution? Is each Side halved? So input of shape (X,Y) is then (X/2 , Y/2)? That is 1/4th of the total pixels. Or is the amount of pixels halved?
@Mythricia1988
@Mythricia1988 5 жыл бұрын
It's not really a strict definition. I think in the overwhelming number of cases, people talk about the horizontal and vertical resolution, in pixels, not total count of pixels. People usually use megapixels as a measure if you are counting the totals... But that word is mostly just used when talking about image sensors or detail level of images. I've never seen "resolution" meaning anything other than x and y dimensions in technicaly imaging or programming.

It would be better to use networks trained for that specific case. I'm sure there are a lot of research to see points in compression/decompression in which neural networks would be useful.

Big problem is DLSS in Battlefield V makes the image look blurry. It's hard to see while there's a lot of movement but it looks terrible when you stand still. Reminds me of the original implementation of FXAA.

Mr Pound. Would there be an image upscaling possible in a future ? The kind of upscaling of images we are seeing nowdays in those futuristic movies where crew of Computer professionals are sitting in front of monitors upscaling stills from a crime scene? Would that be possible in a future with the help of machine learning and linear algebra ?

The thing about perfect upscaling is that you are trying to create information that doesn't exists, which is impossible. In reality what upscaling algorithm are to achieve is a reasonable "guess" of the information that's missing based on the information you have. Long story short, CSI's computers run on Magik.
@TheAudioCGMan
@TheAudioCGMan 5 жыл бұрын
you can recreate actual information if you use multiple frames of e.g. a video. pixels of previous frames maybe fall between pixels of the current frame, so you can insert them there. for that you need motion information with sub pixel accuracy, look for "optical flow" and "super resolution" . temporal anti aliasing (TAA) does something similar but shifts the image actively to get information quickly.

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.

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.
