Using the mouse polling rate test
- Press Start.
- Move the mouse in fast circles over the test area until the 5 seconds are up. A touchpad won’t work.
- Run it two or three times; the readings vary a little.
Reading the results
Average is the number of movement samples per second the browser received. Interval range is the spread of time between samples, ignoring the fastest and slowest 10%. A 1000 Hz mouse should land near 1000 Hz. Some browsers cap events at the screen refresh rate, so 60 or 144 Hz usually means the browser, not the mouse. 8000 Hz can’t be verified in a browser.
Fixes
Use the cable or the mouse’s own receiver, plug it straight into the computer, and check the polling setting in the mouse software.
If one browser reads low, try another before blaming the mouse.
FAQ
What does polling rate mean?
How often the mouse reports its position. 1000 Hz is once every millisecond.
Can a website verify 8000 Hz?
No. Browsers group events and round their timestamps, so very high rates can’t be measured reliably.
Does a higher polling rate reduce all input lag?
It shortens the wait between reports: 8 ms at 125 Hz, 1 ms at 1000 Hz. The sensor, game and display add their own delay.
Why is my result different each time?
Speed of movement, browser load and system timing all shift it. Compare several runs.
