Don't fret if you don't own one of the best graphics cards. Since AMD released its FSR 3 source code a few months ago, modders have been busy creating new mods that inject FSR 3 frame generation into DLSS 3-supported titles. These new mods enable users to run FSR 3 in some games where FSR 3 is not implemented. Digital Foundry reviewed one of these FSR 3 mods and found it can breathe new life into older RTX 20-series and RTX 30-series GPUs, boosting performance up to 75%.
Digital Foundry used a global FSR 3 to DLSS 3 conversion mod that works with any game that supports DLSS 3 natively. Like FSR 2 mods of the past, the FSR 3 mod requires users to inject two new .dll files into a game's directory that features the FSR 3 source code. For RTX 20 and 30 series users, the mod Digital Foundry also has a registry edit to trick Windows into thinking these GPUs support DLSS 3. This is necessary so that DLSS 3 can be activated inside the game, which in and of itself will activate FSR 3 due to the modded .dll files.Digital Foundry discovered fantastic performance uplifts with the FSR 3 mod in action. The review outlet tested several modern AAA titles, including Cyberpunk 2077 and Spider-Man: Miles Morales on an RTX 3080. In Cyberpunk, the RTX 3080 saw an impressive 67% uplift 1440P with DLSS performance upscaling and RT overdrive enabled. Without FSR 3, the RTX 3080 covered around the 60-70 FPS mark, but with FSR 3 enabled, the GPU could achieve over 100 FPS consistently, with frame rates going up as high as 120 FPS.
