Faster frame rates and lower total VRAM consumption with the new frame generation model. Captured in Warhammer 40,000: Darktide on a GeForce RTX 5090, at 4K, with the highest in-game settings, and DLSS Frame Generation
Even with these efficiencies, the GPU still needs to execute 5 AI models across Super Resolution, Ray Reconstruction, and Multi Frame Generation for each rendered frame, all within a few milliseconds, otherwise DLSS Multi Frame Generation could have become a decelerator. To achieve this, GeForce RTX 50 Series GPUs include 5th Generation Tensor Cores with up to 2.5X more AI processing performance.
Once the new frames are generated, they are evenly paced to deliver a smooth experience. DLSS 3 Frame Generation used CPU-based pacing with variability that can compound with additional frames, leading to less consistent frame pacing between each frame, impacting smoothness.
To address the complexities of generating multiple frames, Blackwell uses hardware Flip Metering, which shifts the frame pacing logic to the display engine, enabling the GPU to more precisely manage display timing. The Blackwell display engine has also been enhanced with twice the pixel processing capability to support higher resolutions and refresh rates for hardware Flip Metering with DLSS 4.
Working in concert, our new hardware and software innovations enable DLSS 4 to generate 15 out of every 16 pixels with great image quality, smoothness, and latency.
