Optimizing resource scheduling for Vastarmor RX 9070 XT
Man, once the scheduling was fixed, the jungle details in MHW at 4K looked absolutely insane. Out of the box, the Vastarmor Radeon RX 9070 XT had latency spikes of 110-140ms when swapping high-res textures, causing those annoying frame drops during quick turns. I tried enabling AMD Radeon Super Resolution, but it added some weird chromatic aberration to the edges—definitely a mistake. I ended up disabling low-power states in the driver and locked the motherboard PCIe slot voltage to 3.3V. In RivaTuner, the frame times tightened from 15-30ms down to 10-13ms. Disabling power saving raised my idle temps by 3℃, so I added a small aluminum heatsink to keep it at 45-50℃. Core load is now steady at 65-72% with almost no current fluctuation. After testing various presets, this is definitely the sweet spot, keeping frame times locked at 10-13ms.
