According to NVIDIA, the DLSS 4 can boost performance by up to 8x, and it does that by using "AI to generate up to three frames per rendered frames". In order to maintain responsiveness, it is combined with NVIDIA Reflex. NVIDIA also claims that the DLSS 4 also introduces "the graphics industry’s first real-time application of the transformer model architecture", where the transformer-based DLSS Ray Reconstruction and Super Resolution models use 2x more parameters and 4x more compute to provide greater stability, reduced ghosting, higher details, and enhanced anti-aliasing in-game scenes.

The NVIDIA DLSS 4 will be supported on GeForce RTX 50 series GPUs only and will come to over 75 games and applications on the day of launch.

NVIDIA is also introducing the NVIDIA Reflex 2 with Frame Wrap, which reduces latency by updating a rendered frame based on the latest mouse input just before it is sent to the display. NVIDIA claims up to 75 percent lower latency.

NVIDIA launched a couple of videos showing off DLSS 4 in DOOM: The Dark Ages, Dune: Awakening, and Black Myth: Wukong, as well as DLSS Ray Reconstruction with the new Transformer Model.
