This measures how often your browser receives mouse movement events (Hz). It is a useful proxy to spot obvious issues (e.g., stuck at ~125Hz), but it is not a lab-grade USB measurement.
Understand Hz, stability, and input latency.
Web-based mouse polling tests measure browser-delivered pointer event frequency, not raw USB polling. Learn why ~125Hz appears, why high polling rates are indistinguishable on the web, and how to interpret results.
Think your PS5 DualSense has stick drift? Learn how to connect it to your PC/Mac, visualize stick input, set a deadzone, and confirm drift using our free browser-based PS5 controller test.
Learn the difference between CPS and CPM, what counts as a good click speed, and whether 10-second or 30-second tests are more accurate. Then run our free click speed test and share your results.
Learn what mouse polling rate (Hz) means, the real difference between 125/500/1000Hz, and how to test your mouse polling rate online using our browser-based distribution and stability checker.
Check if your gaming keyboard truly runs at 1000Hz, 500Hz, or 125Hz with our free online polling rate tester and real-time Peak Hz dashboard.
