Tech Focus: Cyberpunk 2077 RT Overdrive - How Is Path Tracing Possible on a Triple-A Game?

Рет қаралды 287,692

Жыл бұрын

How far we've come! Path tracing is the ultimate form of ray tracing and somehow, in just a few years, we've gone from a path-traced Quake 2 to a path-traced Cyberpunk 2077! How is this possible? In this Tech Focus video, Alex explains the combination of hardware improvements since the launch of RTX 20 Series, working in combination with radically more advanced software and the rise of AI-generated pixels - everything coming together to push in-game visuals further than they ever have before.

The fact that we're getting a Triple-A game to implement Path-tracing and be remotely playable (let alone 60 FPS+ abeit with upscaling) is just nothing short of a miracle.

@RicochetForce Жыл бұрын

Bingo. A lot of people were slagging the ever living hell out of Nvidia and Quake back then. But it's clear that Nvidia is playing the long game. We have one of the most visually complex games of all time running realtime pathtracing and it's completely playable. It's borderline surreal to me.

Maybe I’m nitpicking, but I assume you mean real time ray tracing was a dream 25 years ago. Ray tracing itself definitely was a thing, it’s just that a single frame would take hours to render so forget using it in a video game. But even then, it was used in stills and movies (where time wasn’t a factor) and the results at the time were absolutely breathtaking, maybe even more so than today given other technologies couldn’t even come close.

@@jmanig76 But that is the beast to solve. The quality is not really impressive the time in which it is done is. With enough time and physical considerations you would be able to create a photorealistic image. For example comparing the first avatar with the second movie. But to do it in a feasible timeframe or even real time is much harder since you will have to approximate, especially since exponential performance increase at the same price is seemingly ending in our lifetimes.

I remember the Titan Black being able to render a scene at 640x480 30fps (I think it was CUDA accelerated, too). Almost everybody thought path tracing was a pipe dream and without Nvidia's push for dedicated RT cores it would have remained such. The boost in development has been significant and probably unpredictable with pure bruteforcing of CUDA and such.

Yeah, that rate of growth is nuts. By the 60 series it will likely be fully playable on midrange graphics cards.

Another important factor is how BVH travessing inherently works. It has a logarithmic time complexity, which means that if the number of triangles increases by 1000x, the BVH traversal won't take 1000x as long, it might only increase by 2-3x.

thats from graphic cards perspective. But CPU will have 1000x more work to compute BVH, and BVH itself will have 1000x more data- so it will need MUCH more vram. At that size of dataset, you also start to get more cache misses, and need bigger cache. So yeah, in theory 1000x more triangles is not more work to trace, but its still a factor, that we will not see soon (and probably will not need it- looking at ninite)

Large caches are useful for ray-tracing because of the huge acceleration structures (and geometry) required to be consulted during ray traversal, by the aforementioned incoherent rays, and it is expensive to wait on fetches from VRAM. While multi-core GPUs do a great job at hiding these types of latency, they have their limits. Caustic (later purchased by Imagination) had a solution for this, which could be implemented in software to improve cache efficiency: batch rays that are travelling in roughly the same direction, and compute all rays in these batches in a go. This works because there is a high likelihood of traversing the same structural nodes and intersecting with the same set of geometry, improving cache hits dramatically. Another solution is to utilize imposters, reducing the size of both structures and geometry while providing quality high quality results. I believe UE's Lumen does this (as some SDF amalgam) at least in its software mode.

@Keldor314 9 ай бұрын

This is actually a big use case for the shader execution reordering (SER) mentioned in the video. Without going into too much detail, SER lets you reorder and compact threads in a grid according to some arbitrary condition. You could, for instance, reorder threads after tracing indirect rays so that you have groups of threads all executing the same material shader. As for reordering the rays themselves, this would be under the hood, and there's no particular reason to think that Nvidia doesn't already do it. The ray tracing hardware is something of a black box, where shader threads request a ray to be traced, go to sleep, and at some point wake up again when the intersection results are ready.

That if it can run on a Triple A monstrosity like Cyberpunk, it can also run on much smaller, lighter indie fare. For CDPR, they flat out said it's them testing pathtracing ahead of its implementation in Witcher 4 and the next Cyberpunk game (both of which are apparently in simultaneous development). So while while their REDengine is no longer in use, their knowledge and experience with pathtracing will be that much better going into the development of those new games.

As far as I can work out, its still primarily a raster render, ie unlit textures are pasted into the gbuffer triangle by triangle, and then lit, shadowed and reflected using rays. I think they are calling this "full raytracing" because compared to previous titles with RTX features (Shadow of the Tomb Raider, eg, only did shadows with raytracing, not lighting or reflections) it uses all 3 techniques instead of just 1 or 2. IIRC, original Cyberpunk 2077 did reflections with RT but not shadows or GI. TLDR; its not actually "full pathtracing", because real pathtracing wouldn't have any problem with the glass (other than not enough bounces causing dark spots).

An excellent follow up video from DF for CP2077’s overdrive mode. Personally, I would like to see another near/full path-tracing title but on Unreal 5 with high quality Nanite assets for the near future. Currently, the NVidia branch of UE5 is already using RTXGI and RTXDI but has some compatibility issues with newer features such as Nanite trees, so Lumen is still more practical in most cases but has its limitations versus proper path-tracing (ie. Rely on surface cache, light leaking, noise, limited bounces etc).

@alenko4763 Жыл бұрын

I was actually wondering what UE5 can bring together with Nvidias tech. So you’re saying that Nvidia has a dedicated team to implement their tech into UE as good as possible?? That sounds really promising actually

@TheDravic Жыл бұрын

There's so many reasons, think about it for a second. There's actually little reason "not to" do it other than budget, but that's taken care of by incredible sales of this game and Nvidia's involvement. Most of the tech and lessons learned can be applied anywhere, and the technology gets lots of eyes on it because there's a whole expansion coming out for this game later this year and this RT Overdrive mode will be there, ready to go. Both CDPR and Nvidia benefit immensely.

I got the same feeling seeing Overdrive CP2077 as I did playing Mario 64 for the first time, playing GTA 3 for the first time, playing Gears of War for the first time, playing Crysis for the first time. The only way I could describe it is that it feels like I'm seeing the future, now.

Another game I can recommend is metro exodus enhanced. It is also fully raytraced and you can run it maxed out at 4k 120fps with dlss quality on a 4090.

@@gavinderulo12 Metro Exodus Enhanced Edition is nowhere near fully raytraced. Not even close to, tons of shortcuts and fallbacks. And it's very slow to update the light. It's a good example of where we were just a couple years ago but it's not anywhere near as impressive as Cyberpunk 2077 RT Overdrive.

Love raytracing. My only gripe is that in some games, especially hogwarts, things are too shiny and reflective, like they went too far and everything looks wet or clear-coated.
