This allows you to run the frame generator on GeForce RTX 20 and RTX 30
As you know, recently it has been possible to integrate a frame generator from AMD FSR 3 technology into games that support Nvidia DLSS 3. The authors of Digital Foundry decided to test this opportunity from different angles to understand how this solution works viable.
It turned out that everything works very well. For example, in Cyberpunk 2077, a GeForce RTX 3080 video card at 1440p resolution in RT Overdrive mode produces about 100 fps versus 60 fps without FSR 3. In Spider-Man: Miles Morales, performance also increased by 65-75%. That is, the increase is huge, as it should be when using a frame generator, be it FSR 3 or DLSS 3.
As for the shortcomings, sometimes there are still various artifacts that do not exist when activating DLSS 3 directly without any mods. But it seems that often the artifacts are uncritical or even very inconspicuous.
Recall that the specified modification allows you to run the FSR 3 generator on all GeForce RTX video cards, while DLSS 3 is supported only by the latest RTX 40. At the same time, AMD video cards, despite the use of the AMD generator itself, are not supported in such mods, because the game «thinks» that a DLSS upscaler is running, which only works with GeForce cards.
