How to reduce interface latency on Biostar H310MHD3?
My steering inputs were lagging by about 110ms, and that 'mushy' feeling is a complete disaster during high-speed pursuits. Digging deeper, I found that some USB 2.0 ports on the Biostar H310MHD3 were fighting for resources with motherboard Interrupt Requests (IRQ), causing input latency to spike between 30ms - 70ms. I tried swapping out my peripherals for different brands, but the lag followed me everywhere, which made me realize this was a low-level motherboard issue. I headed into the BIOS, forced the USB mode to 'High Power' instead of 'Auto', and killed the 'USB selective suspend' setting in Device Manager. Using an input lag tester, the response time plummeted from 48ms down to 12ms - 18ms. I did hit a snag where my mouse briefly disconnected after the first change, but updating the chipset drivers sorted it out. The southbridge temp sat around 45℃ - 52℃. After a few intense city chases, the controls are finally back to normal and the interface glitch is gone.
