Ray Reconstruction is part of an enhanced AI-powered neural renderer that improves ray-traced image quality for all GeForce RTX GPUs by replacing hand-tuned denoisers with an Nvidia supercomputer-trained AI network that generates higher-quality pixels in between sampled rays.
Trained with 5X more data than DLSS 3, DLSS 3.5 recognizes different ray-traced effects to make smarter decisions about using temporal and spatial data, and to retain high frequency information for superior-quality upscaling.
Trained using offline-rendered images, which require far more computational power than can be delivered during a real-time game, Ray Reconstruction recognizes lighting patterns from training data, such as that of global illumination or ambient occlusion, and recreates it in-game as you play. The results are superior to using hand-tuned denoisers.
In the following scene from Cyberpunk 2077, the inaccurate headlight illumination which surrounds the car is a result of the hand-tuned denoiser pulling in inaccurate lighting effects from previous frames. DLSS 3.5 accurately generates lighting, so you can make out the beam of the headlights, and see light reflect on the curb in front of the car.
With DLSS 3.5, we're delivering a faster, better experience as a free upgrade, building upon the much-loved enhancements already available in your favorite games.
Thanks to RTX, you effectively have the power of 2 computers in your PC or laptop - the first, an Nvidia supercomputer that trains the DLSS AI model with billions of data points, to boost performance and image quality. And the second, your GeForce RTX graphics card, with dedicated tensor cores to execute the AI model in real-time, plus specialized RT Cores, innovations such as Shader Execution Reordering, and the raw power of each RTX GPU, delivering best-in-class ray tracing.
