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. In images shown to media, Ray Reconstruction appears to deliver sharper reflections and textures in supported titles. (See comparisons below.)
