USB Mouserate Switcher lets you enforce a mouse polling rate of 250Hz (4 ms), 500Hz (2 ms) or 1000Hz (1 ms) and lets you restore Windows' original "usbport.sys" (8 ms) if needed.
INSTRUCTIONS: 1. Restart Windows and login to Safe Mode with an admin account 2. Run this utility in SAFE MODE and follow the instructions 3. Reboot your computer
Editor's Note: Anything over 500Hz is probably overkill.
