How to fix resource scheduling on Vastarmor RX 9070 XT?
Riding through the Norwegian snowfields was a nightmare; I was getting these weird 120ms micro-freezes every few seconds, especially during fast camera pans. I checked HWiNFO and saw the VRAM bus on my Vastarmor Radeon RX 9070 XT spiking between 94% - 98% during 4K texture streaming, leaving the GPU core basically idling while waiting for data. I tried enabling 'High Performance' mode in the drivers, but that was a joke—average FPS went up by 3, but the stutters actually got worse. I eventually used MSI Afterburner to bump the memory clock by 200MHz and manually set my Windows page file to 32GB. Looking at the RTSS frametime graph, the spikes dropped from 18-35ms down to a steady 12-16ms. It wasn't a straight path, though; my first attempt at 2600MHz caused some nasty artifacting until I added a 0.02V voltage offset. Now the card sits at 68-74℃ with fans spinning around 1600 RPM. Saved the profile in the driver panel and it's rock steady.
