Mouse polling rate test: This mouse polling rate test estimates how frequently the browser receives pointer events while you move the mouse.
How this mouse polling rate test works
Move quickly and continuously inside the pad for at least two seconds. Use the median as the main estimate and repeat with steady movement. Reset before comparing another mouse or configured rate.
How to read the results
A median near 125, 250, 500, or 1,000 Hz often corresponds with a configured USB polling tier. High-rate devices may be coalesced or limited by the browser, operating system, workload, or display cadence.
Common causes of failed tests
Low or variable results can involve slow movement, event coalescing, browser load, CPU limits, USB hubs, wireless mode, power saving, or a lower rate selected in mouse software.
Troubleshooting before you replace hardware
Move steadily, connect directly, close heavy work, confirm vendor settings, try another current browser, and compare wired mode. A USB protocol analyzer is required for authoritative bus-level measurement.
For setup and buying context, see the mouse test, DPI test, and sensitivity converter.
Frequently asked questions
Is this a USB polling measurement?
No. It estimates browser pointer-event timing, which can differ from the USB report rate.
Why does the result change?
Movement, event coalescing, system load, and browser scheduling affect the sample.
Which number should I use?
The median rate is more stable than the fastest single interval.
