DriftGuard is a new utility for Xbox controllers (and a few PlayStation/Nintendo controllers) allowing firmware-level stick calibration, among other features.
The tool can reportedly unlock manual and automatic joystick calibration for any Xbox controller, fixing stick drift without any hardware tweaks.
Stick drift plagues countless Xbox and PC gamers, and it's not always an easy fix. That's hopefully changing now that DriftGuard has added full calibration support for ALL Xbox gamepads.
