Nvidia just announced DLSS 3, a new generation of its deep learning supersampling technology that will be available on the next generation of Nvidia RTX 40 series graphics cards.
DLSS 3 is a new AI that predicts whole frames instead of just pixels. This time it will even boost CPU-dependent games, and Nvidia showed that ability in Microsoft Flight Simulator.
Nvidia introduced DLSS 3 as part of its GTC 2022 keynote, announcing the technology as part of the benefits of the new RTX 40 series graphics cards. The technology has four components, including a new optical flow accelerator and game engine motion vectors. DLSS 3 processes the previous frame and the new frame, then predicts how the scene changes. As a result, DLSS 3 generates new frames of its own, improving game performance and visuals.
Nvidia promises that DLSS will be 3 to four times faster thanks to the ability to multiply frame rates with its new optical flow accelerator. The new technology actually bundles three different technologies into one, including the DLSS Super Resolution, DLSS Frame Generation, and Nvidia Reflex, which improves responsiveness and significantly lowers latency. This is done by synchronizing the GPU and the CPU, and as Nvidia claims, it can reduce the latency by up to 2 times.
The company’s CEO, Jensen Huang, spoke about the capabilities of DLSS 3 and described the entire process, including how the technology can capture pixel-level information while simultaneously using motion vectors from the game engine to track the motion and geometry in each scene. . . In Nvidia’s example, as shown in the blog post, DLSS 3 was able to reconstruct seven-eight of the total displayed pixels, resulting in a huge performance jump.
DLSS 3 can improve the performance of games that traditionally rely more on the CPU than on the GPU, such as Microsoft flight simulator, because it allows the RTX 40 series GPU to render the game at a much higher frame rate. Nvidia proved this by showing small clips from the game; with DLSS off, frames per second (fps) hovered around 65, but with DLSS 3 on, the game was able to hit 135 fps. The technology was also seen to reach new heights Cyberpunk 2077.
When all is said and done, DLSS 3 will “improve game performance by up to four times over brute-force rendering,” said Jensen Huang. Nvidia will release DLSS 3 in October at which point more than 35 games and applications will support it. There’s also something cool coming out: Portal RTXan updated version of the iconic game, now with DLSS 3 and ray tracing.
In addition to DLSS 3, Nvidia also announced new Shader Execution Reordering (SER) technology that will dynamically reorganize shader workloads to make them more efficient. This technology is said to improve shader performance by up to 2x, providing a 25% in-game framerate boost as a result.
Nvidia is launching three RTX 40 series GPUs: the RTX 4090, available on October 12, and two versions of the RTX 4080 to follow in November.
