Why Latency & Polling-Rate Matter
Every time you move or click, your mouse sends a report to the computer. Polling rate tells you how many of those reports are sent per second (e.g. 1000 Hz = once every 1 ms). Input-lag latency is the delay between your physical click and the moment the operating system registers it. Competitive gamers chase sub-2 ms latency for faster reaction times, but photographers and UI designers also need consistent pointer movement for pixel-perfect work.
- High polling rates smooth out mouse movements.
- Low, consistent latency reduces double-click errors.
- Having mouse jitter often points to cable, USB-hub or sensor issues.
All tests on this site run entirely in your browser — no test data leaves your device. See the about page for more information.
