    Not just games but virtual production. Having path tracing for independent filmmakers. A 2-minute scene that would take 3 days to render on a reasonably powerful machine, (say 4070 super with an i71400) could render in minutes. The time saved that would then go into enhancing the creative process and allow more time for just... thinking and working as a human.. not getting demotivated etc, that time is precious.

    • @richardcowgill-NV
      @richardcowgill-NV Месяц назад +1

      Yeah this is a whole subject I didn't get to touch on, and deserves a separate talk by itself. There are cases where you can get very close to the offline render in terms of quality, 98%+ similar. And maybe you use this technology in a psuedo-realtime fashion to reduce render times. So instead of 5 minutes per frame, maybe its 1-3 seconds per frame. Obviously a huge time savings. Just important to note the things that aren't pathtraced yet, but even then this could still be useful for rapid prototyping.

      @@CrypticWritings89a shader compilation pass can be done as a loading screen, where every mesh, texture, and animation is compiled while a different screen is shown. Level streaming can be done various ways, and distance vs screen space culling can be used to make sure things are loaded and unloaded gradually rather than all at once. All the tools are there, but too many developers release games before spending the time to optimize their games. While the engine could be designed to try and make the best choice on its own, that would require an ungodly amount of development, as the engine would have to optimize on the fly, given a seemingly endless number of possible scenarios for all levels and their overlaps. Meanwhile, a team could move from outside of a building to inside, and change the streaming and culling methods used, and try again to see which method provides the best performance. This is a developer issue, not an engine issue.

      I may be in the minority here but i feel the trade-off for path traced direct and indirect is very worth it. Is "temporal" simply means looking at previous frames to predict future frames. It's the most logical way of achieving such technologies and doesnt have to necessarily mean artifacts either just because it is temporal. These artifacts may very well just be coming from the denoiser thats being used and not necessarily from ReSTIR

    Since it's not path tracing everything, nvidia should call this hybrid path tracing. It is defaulting to ray trace and raster in quite a lot of cases. In general, when someone mentions path tracing, we expect a modern offline path tracer that can handle refraction, translucency, high quality sss, layered materials, hair, vdb, and everything else at multiple bounces.

    • @chasingdaydreams2788
      @chasingdaydreams2788 Месяц назад +13

      The point is that MOST things are path tracing- direct and indirect lighting which makes up most of use cases. Saying it is defaulting to ray tracing in a lot of cases is such a disservice to the 80% of the scene that is being path traced. The main things that dont get path traced is low roughness, transclucency, fog and dof. Which in generally only make up 30% of scene. At the end of the day, almost every scene you have is going to look SIGNIFICANTLY better with this technology. Furthermore, i really dont think anyone should expect to click on this video expecting everything to be path traced and for this to be fully featured coming from nowhere. The fact that the made this compatible with unsupported use cases is a big deal on it's own. Again please lets not do a disservice to such an incredible leap in graphical fidelity

    I might be the only one but I can't say I'm impressed. Especially on Meerkat demo. If we compare to the original here : ruclips.net/video/SB4nnhJv3IU/видео.html (compare 34:55 here with 0:08 on the link) there is far far less GI on rocks in general making the render more video game like and unpleasant. The other thing that I don't like is that I see a lot of problem Lumen currently have in the RT Pathtrace render. Like GI poping, Specular glitching and defocus being a little bit unstable.
    I am ofc very interested with the techno and hope it will get better with time but I do not feel any hype from what I see. I see no gain in being realtime Pathtrace 60fps if you have to sacrifice everything that make an image good.
    Honestly (working in animation right now) I see more value on fixing Lumen with MRQ & Temporal than developping a real time PathTrace.

I hope someone asked a question about that at the talk, because compared to the original meerkat demo the shadows in the nvidia demo are going to almost black. In all fairness, gpus are probably not fast enough to handle path tracing in real time, because here they're only path tracing certain things. They're also using a lower resolution, incredibly low samples, strong denoising etc.

It is coming soon for a year now.

    I love all of this, and I love Richard's presentations (been watching them for a long while). The only barrier to entry here is needing to have the separate branch. In the past I'd downloaded the branches and compiled, but it's a bit limiting as far as other aspects of Unreal that are easily injected into the vanilla code from Epic Games. I wish Nvidia and them could work together so everything could be a plugin, similar to how they now have DLSS available as a directly-injected plugin. Obviously that would be vastly more complex than I myself could understand, but it would be an 'ideal' situation. I HORRIBLY miss all of Nvidia's GAMEWORKS library not being supported anymore (for a long, long time). :( Love the tech, Nvidia!!

    Good showcase but please also talk about the caveats. We can see how this looks in motion. Show some bad cases, show the ghosting, the smearyness. It comes off as a bit shill-y and dishonest to not mention the negatives of these techniques. It's not only a performance hit. The image stability and motion clarity takes a huge noisedive in many cases. This is like 2015 era TAA all over again 😂

    Now... it would be interesting, what exactly is considered high-end or low-end hardware. But looks very promising!
    What is a bit concerning tho is the fact that companies might rely too much on things like DLSS for performance, instead of optimizing their games properly. Actually, thats already happening. On the other hand, the more streamlined and optimized the engine is out of the box and the less you can do to break performance (like with the light sources), the better.
