Controller Update Rate Test
Keep a stick moving and this measures how frequently fresh data reaches the page — a browser-observed update rate, not a hardware polling certificate.
Controller status
No Controller Detected
Connect your controller using USB or Bluetooth and press any button.
- Browsers only reveal a pad after it sends its first input — press a face button or move a stick.
- Both USB and Bluetooth work. If nothing appears at all, reconnect the controller and press a button with this page focused.
- Some remapping tools claim the pad before the browser sees it. If nothing shows up, try closing them and reloading.
- Chrome or Edge expose the most controller features, including vibration.
Browser update rate
How often this browser shows fresh data from your controller
Connect a controller to measure update rate.
Troubleshooting
Controller not detected? Work through this checklist
Nine checks covering focus, cables, Bluetooth pairing, background software, DS4Windows virtual controllers and browser support — open it only if your controller is not showing up.
What is really being measured
The page counts how often the controller's reported timestamp changes and turns those intervals into a frequency. That is a genuine measurement of what a web page receives.
It is not the same as the raw USB polling rate. Browser animation timing, your monitor's refresh rate, the operating system, Bluetooth scheduling and background load all cap the observed figure.
Reading the numbers honestly
Jitter matters more than the headline Hz. Steady intervals mean predictable input; erratic intervals are what actually feel bad while playing.
No web page can certify that a controller truly polls at 1000 Hz. Treat this as a stability check, not a benchmark score.
Frequently asked questions
- Why do I only see around 60 Hz?
- Most browsers deliver gamepad updates in step with the display refresh rate. On a 60 Hz screen that caps what any web page can observe, regardless of the controller.
- Is Bluetooth slower than USB here?
- Usually, and it also tends to show higher jitter. Testing both connections on the same pad is a fair comparison.
- Does a higher number mean better input lag?
- Not directly. Total latency includes the game, the display and the operating system; this only measures update frequency reaching the browser.
- Why does the result change between runs?
- Background tabs, power saving and CPU load all affect browser scheduling. Run it a few times and use the typical result.
