Fixing driver instability on Sapphire PURE RX 9070 XT 16G?
This is unbelievable. I bought a top-tier card, but the game turns into a slideshow the moment I use an ultimate—it makes me want to uninstall the whole thing. The Sapphire PURE RX 9070 XT 16G had a nasty compatibility conflict with the latest drivers, causing frame times to explode from 7ms to 120ms during skill triggers. I tried updating Windows patches first, but that did nothing for the lag and actually slowed my boot time by 10 seconds—a complete waste of time. I eventually used DDU to wipe everything and rolled back to a stable driver version from three iterations ago, while also disabling the built-in overlay services. Monitoring with RTSS, frame times returned to a healthy 6-11ms range, and the jarring stutters are completely gone. I did notice that my max FPS at 4K dropped by about 5 frames after the rollback, but that's a tiny price to pay for a game that actually runs. Now, the GPU core stays at 64-69℃ and VRAM is between 78-83℃. I've backed up the system image to keep the VRAM temps in that 78-83℃ range.
