AMD is looking into new techniques for upscaling and denoising, possibly gearing up for the release of the next version of FSR.
Nvidia overwhelmingly dominates the list of the best graphics cards, and that largely comes down to its feature set that’s been enabled through DLSS. AMD isn’t sitting idly by, however. The company is researching new ways to leverage neural networks to enable real-time path tracing on AMD graphics cards — something that, up to this point, has only really been possible on Nvidia GPUs.
When enabling path tracing in a game like Alan Wake 2 or Cyberpunk 2077, you’re only getting a small fraction of the rays cast into the scene. In a real-time context, only a handful of samples per pixel are cast into the scene, and they bounce around, but rarely go back to a light source within the scene. That leads to a noisy image — see the top left of the image above — that needs to be cleaned up with denoising. AMD is applying a neural network to the denoising process.
