FSR only works (looks decent) if you set your display to it's native resolution in game.
I suggest setting it to native in the driver too. Any other setting will make the game look
like chicken turd smeared on a wet wall, regardless of what quality you set. I didn't like
it at all and reverted to the old upscaler. Looks much better, doesn't cook my PC and I
get +5 fp/s to boot. I also use the drivers sharpening to get things crisp again.
