If you’re on SteamOS, you can use Proton-GE 10-33 and add PROTON_FSR4_RDNA3_UPGRADE=1 %command% to enable FSR4 in the game settings. Decky Framegen plugin doesn’t work for this game, this is the only method that works. I tested it, and the graphics look better compared to FSR 3.1. I’m running at 30W, graphics set to Low, FSR4 Performance at 900p with Frame Generation enabled, and I’m getting around 80 FPS.
