> Are tensor cores idle during 3D gaming? The tensor cores are used for real-time raytracing, ML-based anti-aliasing during gaming, and other features. The Turing whitepaper has a lot of information on that. https://www.nvidia.com/content/dam/en-zz/Solutions/design-visualization/technologies/turing-architecture/NVIDIA-Turing-Architecture-Whitepaper.pdf https://www.nvidia.com/content/dam/en-zz/Solutions/design-vi... A more generic answer to this question is that everything NVIDIA puts in their GPUs is for the gaming market. Other use cases are incidental.

I think the ray tracing cores may be separate, they accelerate BVH traversal and intersection.

  The tensor cores are used to denoise the raytraced result.

Between the 30% framerate hit and the (to me) barely-perceptible visual difference, real-time raytracing still feels like a gimmick.

  The new Minecraft stuff is the very first time I've seen raytracing produce graphics that make my brain conceive this could be a "realistically lit" scene, and it doesn't even take advantage of things like significant amounts of reflection and re-reflection. HOWEVER, I see zero benefit to the actual game from that.

    In the case of Minecraft no new graphics feature is really going to benefit the "actual game", but players who obsess over their created spaces might really appreciate having better lighting that they can control through things like reflectivity. It's something you'd have to poll the average teen-who-still-plays-Minecraft about though.

    Have you tried the many advanced shader packs that've been available for years and don't need raytracing? https://youtu.be/JJeb1eEZYhI https://youtu.be/JJeb1eEZYhI

  If you haven't seen any screenshots of it at work in Remedy's Control, it's pretty nice there. Nothing groundbreaking but it's the first time I went 'oh!' and realized that I was seeing stuff that would've been invisible without raytracing. It's used for shadowing, reflections on glass, and a bunch of other stuff that ties the scene together and ensures things are where you expect them to be. I expect we'll see some more compelling uses of it in the next few years, given that it took until the last year or so to see games start using it in a way that wasn't just tacked on. (It makes sense that Control was one of the first titles to use it extensively, since they were publishing talks about GPU raytracing well before the hardware was in anyone's hands)

  We're in an awkward transition period where hardware raytracing is now available but not very useful for most people as the hardware is still niche and getting the most incredible results from it doesn't run at 60+ fps. But, if we ever want games/VR/AR/etc. to match the photorealism of modern visual effects, full-blown raytracing / path tracing will be required. It's going to take a while but it will eventually happen. The results will look far different than the before/after screenshots in the Turing paper. Also, once the hardware is more ubiquitous (e.g. in consoles), some of the features provided by raytracing will make the game development process much simpler even if the results are only marginally better for some of the presented hybrid use cases.
