Along with the Ada Lovelace architecture and GeForce RTX 4000 graphics cards, NVIDIA announced DLSS-3 scaling technology, which the company estimates can boost gaming performance by four times (compared to traditional rendering at the target resolution). NVIDIA promises rapid adoption of the new technology, with the first DLSS 3-enabled games due out in October.
DLSS 3 is the next evolution in NVIDIA’s family of AI scaling algorithms. The difference between DLSS 3 and previous versions of the technology is that when the resolution is increased, this technology can now not only generate additional pixels in existing frames, but also build up completely new intermediate frames. In addition, DLSS 3 integrates NVIDIA Reflex technology, which optimizes the response time.
When upscaling, DLSS 3 works with four types of data: current and previous frames, optical flow field, and game engine data – motion and depth vectors.
The optical flow field is a completely new element in scaling technology, it is generated by the optical flow hardware accelerator added to the Ada Lovelace architecture. Optical flow analysis involves comparing frames sequentially and identifying relationships between the movements of pixels and objects (particles, reflections, shadows, etc.). By comparing this data with motion data from the game engine, you can accurately reproduce the changes in geometry that occur in the scene.
The AI algorithm embedded in DLSS 3 analyzes the information received from all sources and selects which data is best used for scaling and building up intermediate frames in each case.
DLSS 3 actively leverages the hardware capabilities of the Ada Lovelace architecture – not only an optical flow accelerator, but also new fourth generation tensor cores. Therefore, DLSS-3 technology is dependent on the new architecture and will only be available on GeForce RTX 4000 series graphics cards.
NVIDIA showed how DLSS 3 works using the example of the pre-release version of Cyberpunk 2077. When DLSS 3 was activated, the FPS increase reached a fourfold value and the frame delay was halved, without a visible decrease in image quality.
The great advantage of DLSS 3 is that with this technology you can increase the frame rate even if the CPU is the bottleneck in the system. By creating intermediate frames, you can increase FPS in processor-dependent games with a large open world. For example, in a demo in Microsoft Flight Simulator, the frame rate doubled when DLSS 3 was enabled.
NVIDIA also shared summary results from DLSS 3 performance tests in a number of other games.
DLSS 3 technology has been endorsed by leading game and engine developers, with more than 35 games including A Plague Tale: Requiem, Cyberpunk 2077, Microsoft Flight Simulator and Warhammer 40,000: Darktide in the first phase.
