A new mod has popped up on the Nexusmods library that attempts to replace NVIDIA’s DLSS with AMD’s FSR 2.0, in order to make the game more fluid for the vast majority of gamers with non-RTX GPUs. Although still in development, it has produced very promising results, boosting frame rates by as much as 2x on a GeForce GTX 1080 at 4K. The six-year old graphics card is now able to deliver a rather impressive 45 FPS at 4K with FSR 2.0 enabled.
This mod works by simply replacing the NVIDIA DLSS .dll file, replacing it with a custom one that allows the implemenation of FSR 2.0…on all PCs. As such, there’s no option for FSR 2.0 in game, and turning on DLSS enables it instead. Since both the upscalers are temporally enabled samplers, the mechanism is very similar, and the two are are inter-changable.
This method should work with every game with DLSS support with some simple tweaks to the .dll file. Keep in mind that there are some features of vanilla FSR 2.0 that aren’t implemeted by this mod, but it’s still a fair bit better than FSR 1.0. Furthermore, it also works with the Steam Deck and Linux, making handheld gaming a lot more smoother.
