How to fix blurry edges in Silksong on a Sapphire RX 7800 XT?
Using a 7800 XT for a 2D game is total overkill, but for some reason, FSR Quality mode introduced this annoying ghosting and blur around the characters, which is super obvious against the black backgrounds. The Sapphire Radeon RX 7800 XT 16G sampling rate was over-smoothing the 2D vectors, killing the sharpness by about 15%. I tried disabling all anti-aliasing, but the game turned into a jagged mess—I actually had to laugh at how bad it looked. I then dove into the AMD Adrenalin software, cranked Radeon Image Sharpening up to 70%, and forced the in-game render resolution to 100%. The edges snapped back to being crisp, and the noise was gone. I did notice some weird white halos around small particles at 70%, so I dialed it back to 62% for the sweet spot. GPU temps are chilling at 52-58℃, and fans are barely spinning at 1400-1600 RPM. I exported the sampling logs to verify the fix.
