GamePad GaugeGuides
Explanations behind what our tools measure — controller stick drift, deadzone, polling rate, and button mapping — written with sources cited throughout.
- Why Isn't My Controller Detected in the Browser? A Troubleshooting Guide
The Gamepad API deliberately hides connected controllers until you interact with them. Here's why, and what else to check if a controller still won't show up.
- Xbox vs PlayStation vs Switch Pro Controller: Button Mapping Explained
How the browser's Standard Gamepad layout maps buttons by physical position rather than printed label, and how that translates across Xbox, PlayStation, and Switch Pro controllers.
- Controller Polling Rate Explained: What Hz Actually Means
What polling rate measures, why USB devices historically default to 125Hz, why 1000Hz controllers exist, and why a browser can't measure the raw hardware number.
- What Is Controller Deadzone? A Practical Guide to Setting It Right
What deadzone actually does, why it exists, how it's implemented differently across engines, and how to measure a good value for your own controller.
- Why Do Analog Sticks Drift? Causes, Fixes, and How to Test For It
What causes controller stick drift, why it's a well-documented hardware wear issue rather than a software bug, and how to test for it, work around it, or fix it.
