What is Controller Polling Rate (Hz)?

Controller polling rate refers to how many times per second your gamepad sends data to your PC. Measured in Hertz (Hz), a higher polling rate means lower input lag. Standard controllers operate at 125Hz to 250Hz out of the box (4-8ms delay). Competitive gamers overclock to 1000Hz (1ms delay) for games like Call of Duty or Apex Legends.

What is Circularity Error?

Analog stick circularity is a crucial metric for controller accuracy. When you rotate the joystick along its physical outer edge, a perfect controller will draw a flawless circle in the software. Any deviation is measured as an "Error Rate." Standard controllers usually have an error rate of 5% to 15%.

What is Deadzone Testing?

A deadzone is the central area of your analog stick where movement is not registered by the game. This prevents "stick drift" when you aren't touching the controller. Use the Deadzone Overlay slider above to map out exactly when your stick movement breaks out of the deadzone (Status turns green) to perfectly configure your in-game settings.
