Faster frame rates and lower overall VRAM consumption with the new generation frame model. Taken in Warhammer 40,000: Darktide on a GeForce RTX 5090, at 4K, with the highest game settings and DLSS frame generation

Despite this efficiency, the GPU still needs to run 5 AI models via 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 slowdown. To achieve this, the GeForce RTX 50 series GPUs feature 5th generation Tensor cores with up to 2.5x more AI processing power.

Once the new frames are generated, they will play evenly to ensure a smooth experience. DLSS 3 Frame Generation utilized CPU-based timing with variability that can worsen with additional frames, resulting in less consistent frame timing between frames, impacting smoothness.

To handle the complexity of generating multiple frames, Blackwell uses hardware flip metering, which offloads frame pacing logic to the display engine and allows the GPU to control display timing more precisely. The Blackwell display engine has also been expanded with twice the pixel processing capacity to support higher resolutions and refresh rates for hardware flip metering with DLSS 4.

Working together, our new hardware and software innovations enable DLSS 4 to generate 15 out of 16 pixels with excellent image quality, smoothness and latency.
