How to reduce USB latency on Soyo SY-A320D4+ in Marvel Rivals?
In a competitive game, a few milliseconds are everything, so I was pretty meticulous about this. I updated every single driver first. My latency tester showed response times jumping erratically between 12ms and 25ms, which is lethal when you're trying to land a fast combo. I tried disabling Windows power management, but that only shaved off 2ms and didn't stop the spikes. I realized the issue was the motherboard's underlying USB polling mechanism. I went into the BIOS, disabled all USB power-saving modes, and enabled High Performance mode. The response time finally stabilized at 8-11ms. I did notice some slight mouse drift initially, but locking the sampling rate to 1000Hz fixed it. Chipset temps are sitting at 42°C - 47°C, and the precision is night and day. I verified the timestamps using a professional latency analyzer to make sure the lag was actually gone.
