How to fix scheduling lag on VastArmor RX 9070 XT in Project Orion?
Cruising through the skyscrapers of Night City, I kept hitting these rhythmic micro-pauses—it felt like a scratched DVD. The VRAM clock on my VastArmor Radeon RX 9070 XT Super Alloy was fluctuating between 2.1-2.3GHz, but during complex lighting scenes, the driver scheduling latency hit 18-22ms, leaving the CPU idling while waiting for the GPU. I tried disabling all overlays, but it did absolutely nothing, which told me I needed to tackle the clock strategy at the driver level. I went into AMD Adrenalin, locked the VRAM clock to its maximum frequency, and switched the Windows power plan to 'Ultimate Performance'. RivaTuner showed the frame time spikes drop from 42ms down to a manageable 12-15ms. The only catch is that idle power draw jumped by 15W, but I fixed that with a custom low-load downclock curve. GPU temps are sitting at 66-72℃. After four hours of testing, the stutters are gone.
