Why is my Razer mouse skipping in Overwatch 2?
This one was incredibly elusive. I checked the RZR-SENS-22 EMI analysis and used AIDA64 to monitor the motherboard's USB rail. I found that during flick shots, the voltage would dip by about 0.1V, causing the sensor to drop frames. I went to Device Manager, disabled 'Allow the computer to turn off this device to save power' for the USB hubs, and flashed the March 2026 firmware. The cursor offset dropped from 5px to under 1px, making it feel rock steady. However, on cheap cloth pads, I still see some jitter, proving that sensor precision is as much about physical surface friction as it is about voltage.
