NVIDIA's DLSS 3.5 makes ray traced games look better with AI

Last year, NVIDIA unveiled DLSS 3 with frame interpolation, which used its AI-driven rendering accelerator to add extra frames to games. Now at Gamescom it's introducing DLSS 3.5, which adds Ray Reconstruction, a new feature that will use the company's neural network to improve the quality of ray traced images. It'll be available for all RTX GPUs--unlike DLSS 3's frame interpolation, which only works with RTX 40-series cards. NVIDIA says Ray Reconstruction will replace "hand-tuned denoisers with an NVIDIA supercomputer-trained AI network that generates higher-quality pixels in between sampled rays." That's similar to NVIDIA's original pitch for DLSS -- making low-res textures look better thanks to AI -- and it could potentially lead to better ray tracing performance as well.
