The RTX 4090 won’t be available until mid-October, which is also when performance reviews are published. In this regard, the information Digital Foundry provides today is similar to what NVIDIA has already presented, but with relatively more depth. Those anticipating DLSS3 pixel analysis will be dissatisfied, but those who want to check how much faster DLSS3-compatible games can run will undoubtedly find something interesting.
Cyberpunk 2077 (Overdrive RT version), Spider-Man: Remastered, and Portal: RTX have been made available to Digital Foundry. All three games have DLSS 3 support, although only reviewers can access them at the moment. It’s important to note that even when DLSS3 upgrades are released, GeForce RTX 30 and 20 GPUs won’t support the technology (at least not now).
Digital Foundry was not allowed to display frame rates. However, they were allowed to compare performance with percentages. The 30 minute post and video are essentially a demonstration of DLSS3 in action, with comparisons to native and DLSS2 imagery. Depending on the game, CPU limitation and whether recording was active, DLSS3 can improve performance by 2x to 5x.
DigitalFoundry claims that NVIDIA DLSS3 generates full frames based on game data such as motion vectors and optical flow analysis. Buffering frames adds additional latency. This issue can be solved using NVIDIA’s Reflex technology, which is now part of DLSS3. A cursory examination of frame times reveals that the latency is more than DLSS, but less than directly generated frames. These results are based on limited testing and a single resolution, so they may vary.
This performance study will most likely be supported with a detailed dive into DLSS3 technology once the review embargo is lifted.
