Fixing texture blur on Sapphire RX 7800 XT Polar Edition
Tearing through neon streets only to see buildings look like smeared paint is an absolute mood killer. Even with the 16GB on the Sapphire RX 7800 XT Polar Edition, the driver was choking on 4K texture calls, causing GPU utilization to swing violently between 40% and 95%. I tried increasing the Windows page file to 32GB, but that was a complete waste of time—it actually made the stuttering worse. I eventually gave up and used DDU to wipe every trace of the old drivers, installed the latest WHQL version, and manually purged 5.4GB of shader cache. Using RivaTuner, I saw frame times shrink from a jagged 16-50ms to a smooth 11-14ms. The textures snapped back into focus immediately. Just a heads-up: the first boot after clearing the cache took forever while shaders recompiled. Now, VRAM usage is steady at 11.2-13.5GB and temps stay at 64-69℃. The game finally feels responsive, and the input lag is gone.
