Redditor “NarutoUA1337” pulled this off by porting the FSR files from another unmentioned game. In the video, you can see a number of modes running with each implementation. 0.5x (running at half-res and scaling up) is “performance mode”, and 0.75x (running at three-quarter resolution and scaling up) is “quality mode”. It does take a few seconds for your eyes to adjust, but there is a noticeably sharper image in FSR mode. This screenshot comparison really shows off the difference if you want to compare the two at your leisure. The ground textures are noticeably less blurry using FSR upscale. Quite a win. FSR does drop a couple of frames, but as you’re already claiming a significant frame rate boost overall by upscaling, there’s really no reason to settle for the game’s native version, unless you’re worried about being banned in multiplayer. This hasn’t been tested in GTA Online, so if you want to be cautious it’s best to not install it on that for now. Others will try, no doubt. You can download the mod here.
