How to fix driver conflicts on Sapphire RX 9070 XT?
The second I stepped into the Shadow Realm, my FPS collapsed from 90 down to 45, which told me immediately that my current driver version was a mess. The Sapphire PURE RX 9070 XT core clock was bouncing between 2400-2600MHz, but the default AMD Adrenalin scheduling was hitting a major instruction conflict with the complex shadow sampling. I tried turning on RSR (Radeon Super Resolution), but it just added hideous aliasing to the edges and only gained me 5 FPS—totally not worth the visual trade-off. I ended up wiping the drivers and rolling back to the previous stable version, then disabled Radeon Anti-Lag and set texture filtering to Performance mode. My 1% lows jumped from 32 FPS to 58 FPS, making the game feel way more consistent. I did run into some brief black screen flickers after the rollback, but that disappeared once I manually set my monitor refresh rate to 143Hz. GPU temps are 62-68℃ and fans are at 1200-1500 RPM. 3DMark Steel Nomad confirms I'm back to peak performance, and memory temps are 58-63℃.
