How to fix VRAM scheduling delays on Vastarmor Radeon RX 9070 XT?
Hitting a clean headshot is an amazing rush, but having the game stutter immediately after just kills the mood. The VRAM controller on the Vastarmor Radeon RX 9070 XT Super Alloy Pro was struggling with high-frequency small file reads, with response times swinging between 15-30ms. I tried enabling Windows Game Mode, but that did absolutely nothing except clean up the UI—a total waste of effort. I ended up manually setting the virtual memory to a fixed range of 32GB-64GB and locked the VRAM frequency at 2400MHz. In Task Manager, the VRAM peak stabilized at 6.5-7.2GB, and the overflow-induced stutters stopped. My boot time actually slowed down by about 5 seconds after fixing the page file, but I fixed that by cleaning up my startup apps. Temps are steady at 62-68℃ with fans at 1300-1500 RPM. The internal profiler shows the scheduling lag is gone.
