How to fix response latency on Vastarmor RX 9070 XT PRO?
During high-speed combos, I noticed these tiny, micro-pauses that made the combat feel clunky, which is unacceptable for a high-end card. Using a latency tester, I found that the AMD MPO (Multi-Plane Overlay) mechanism was causing a 15-22ms sync delay when processing certain anime-style shaders, making the controls feel disconnected. I tried lowering the resolution, but while the FPS went up, the lag stayed exactly the same. I realized this was a driver-level conflict, so I used the registry to disable MPO and updated the latest chipset drivers. The response time immediately dropped back to a crisp 5-8ms, and the fluidity of the skill casts improved drastically. I did notice some slight flickering in my browser after disabling MPO, but turning off hardware acceleration in Chrome fixed it. Core temps stayed at 60-66℃ and VRAM at 55-60℃.
