How to fix VRAM scheduling lag on Vastarmor RX 9060 XT?
The tearing lines were incredibly obvious whenever I flicked the camera, making these massive war scenes look like a broken slideshow. Even with 16GB of VRAM, the default driver scheduling on the Vastarmor RX 9060 XT was introducing a 12-18ms sync delay at 4K. I tried enabling Enhanced Sync in-game, but that just turned the controls into mush—it felt like I was wading through mud, which is a complete dealbreaker for a shooter. I ended up nuking my old drivers with DDU and installing the latest factory version 26.1.0, then switched AMD FreeSync to 'Enhanced' mode. Monitoring via RivaTuner showed frame times dropping from a chaotic 15-30ms down to a tight 9-13ms, and the tearing finally stopped. I did hit a snag where the screen flickered for a bit after the update, but a quick reinstall of my monitor's color profile fixed it. The GPU now stays between 62-70°C with fans humming at 1400 RPM. After comparing the results, the sync is finally spot on, and the GPU temp remains a cool 62-70°C.
