How to Test DualSense
- Connect your DualSense via USB-C cable or Bluetooth to your PC/Mac.
- Press any button or tilt either thumbstick to wake up the Gamepad API connection.

- Rotate both thumbsticks 360° to test circularity error and outer margin bounds.
Frequently Asked Questions
Q: Why does my PS5 DualSense controller drift when I am not touching it?
DualSense controllers use ALPS potentiometer joysticks where metal wipers physically slide across resistive tracks. Friction wears down these tracks over time, shifting the resting neutral point.
Q: What is the default polling rate of a PS5 DualSense on PC?
Over Bluetooth and standard USB, the DualSense defaults to a 250Hz poll rate (4ms interval). Custom drivers on PC like DS4Windows can push a wired connection up to 1000Hz (1ms).
