Fixing performance dips on Vastarmor Radeon RX 9070 XT
It's honestly a joke that a high-end card like this would have such erratic frame swings. The Vastarmor RX 9070 XT was hitting transient voltage drops around 1.1V when processing specific particle effects, causing the clock to bounce between 2200MHz and 2600MHz. I tried using sampling scaling, but that just introduced hideous aliasing on the edges—a terrible trade-off. I finally went into the driver settings and applied a +50mV core voltage offset and locked the minimum frequency at 2000MHz to kill the scheduling lag. AIDA64 showed temps rise from 72℃ to 78℃, but the FPS became rock solid. I did have one crash ten minutes into the game after the first tweak, so I had to drop the max frequency by 50MHz to stabilize it. The input response now feels incredibly snappy and responsive. I've backed up this voltage profile, and the system is finally optimized.
