Mouse Polling Rate Test

What it is

Mouse Polling Rate Test is a free browser-based utility that measures how often your mouse reports its position to your computer. The tool counts browser-visible movement samples and provides metrics including average rate, peak rate, jitter, and stability across polling rates from 125Hz to 8000Hz.

The test requires no installation and runs entirely in your browser. Users move their mouse continuously during an 8-second sampling period to generate measurements. The tool is designed for gamers and hardware enthusiasts investigating input event timing and peripheral behavior.

Results reflect browser-observed update rates and may differ from hardware-level tools, particularly at very high rates. The site emphasizes that a low browser reading alone does not establish a hardware problem, as measurements depend on the browser, operating system, device settings, and test performance.

Questions from the bench

What is mouse polling rate?

Polling rate is how often your mouse reports its position to your computer. A 1000Hz rate means the mouse sends data every 1 millisecond, lowering input latency and improving tracking.

How accurate is this browser test compared to desktop software?

The test counts browser-visible movement samples including coalesced samples. It cannot verify every USB poll or diagnose a faulty mouse, and a low reading alone does not establish a hardware problem.

Why is my polling rate unstable?

The observed update rate may reflect browser delivery limits. Try another browser and repeat; this does not mean your mouse runs at the displayed rate. A match with page frame timing is a clue, not proof of a monitor or mouse fault.

How do I interpret the stability score?

Stability is 100 × max(0, 1 − standard deviation / mean) of update rates in complete 500 ms windows. It describes this capture, not mouse quality or gaming performance. Lowest 500 ms rate is the minimum rate among those complete windows.

Does 8000Hz make a difference?

The jump from 1000Hz to 8000Hz can improve micro adjustments on high refresh monitors, but it also requires a strong CPU and stable USB setup to avoid dropouts.
