Accelerated by DLSS 3ĭLSS 3 complements groundbreaking advancements in path tracing and harnesses modern AI - built on GPU-accelerated deep learning, a form of neural networking - as a powerful gaming performance multiplier. It wasn’t until GeForce RTX 40 series and DLSS 3 was available that it was possible to bring path tracing to real-time graphics.Ĭyberpunk 2077 also taps into Shader Execution Reordering - available for use on the NVIDIA Ada Lovelace architecture generation - which optimizes GPU workloads, enabling more efficient path-traced lighting. Path tracing has been one of the main lighting algorithms used in offline rendering farms and computer graphics in films for years. Path tracing is the final frontier for the most physically accurate lighting and shadows. More recently, in 2018, NVIDIA introduced RTX GPUs to support ray tracing. Since the 1970s, video games have relied on rasterization techniques (see below). In gaming, which requires fast frame rates, rendering needs to happen in about 0.016 seconds. While long used in computer-generated imagery for movies, path tracing there took place in offline rendering farms, often requiring hours to render a single frame. Decades of Research Uncorkedĭecades in the making, real-time path tracing is indeed a big leap in gaming graphics. And the influence on video games is just the start, as real-time path tracing holds promise for many design industries. Like with ray tracing, it’s expected many more will follow. Coming shortly after path tracing for Minecraft, Portal and Quake II, it underscores a wave of adoption in motion. Natural colored lighting also bounces multiple times throughout Cyberpunk 2077’s world, creating more realistic indirect lighting and occlusion.Ĭyberpunk 2077, previously an early adopter of ray tracing, becomes the latest modern blockbuster title to harness real-time path tracing. With full ray tracing, now practically all light sources cast physically correct soft shadows. This technology preview, Cyberpunk 2077’s Ray Tracing: Overdrive Mode, is a sneak peek into the future of full ray tracing. “This not only gives better visuals to the players but also has the promise to revolutionize the entire pipeline of how games are being created,” said Pawel Kozlowski, a senior technology developer engineer at NVIDIA. But until the arrival of GeForce RTX GPUs with RT Cores, and the AI-powered acceleration of NVIDIA DLSS, real-time video game path tracing was impossible because it is extremely GPU intensive. It’s used by visual effects artists to create film and TV graphics that are indistinguishable from reality. Path tracing, also known as full ray tracing, accurately simulates light throughout an entire scene. Game developer CD PROJEKT RED today at the Game Developers Conference in San Francisco unveiled a technology preview for Cyberpunk 2077 with path tracing, coming April 11.
