Polling Rate questions, fixes and result guides.
Practical answers for common polling rate problems, confusing results and setup questions — with a direct path back to the live test.
Is 500 Hz or 1000 Hz mouse polling better?
1000 Hz can report pointer updates more frequently than 500 Hz, but the practical benefit depends on the game, display refresh rate, CPU load and input pipeline. A stable 500 Hz can feel better than an unstable higher setting.
Why does my 1000 Hz mouse show less than 1000 Hz?
Browser event coalescing, USB scheduling, tiny pointer movements, power saving and system load can reduce the observed event rate. Use large continuous movements and compare several runs before treating the result as a hardware problem.
Can a browser accurately test 4000 Hz or 8000 Hz mice?
A browser can estimate very high event cadence, but it is not a direct USB hardware analyzer. At 4000–8000 Hz, event coalescing and scheduling make browser-observed results more sensitive to system and browser behavior.
Why can a 1000 Hz mouse show less than 1000 Hz?
Browser event coalescing, USB scheduling, operating-system load, drivers and pointer movement quality can lower the browser-observed rate even when the device is configured for 1000 Hz.
Can a browser accurately verify 4000 Hz or 8000 Hz polling?
It can observe high-frequency pointer events, but a web page is not a USB hardware analyzer. Very high rates are more likely to be limited or coalesced by the browser and operating system.
How accurate is this polling rate tool?
This is browser-observed input frequency, not a direct hardware USB polling certificate.
What should I do if the polling rate result looks wrong?
Use a focused foreground tab, avoid tiny movements that trigger acceleration pauses and retest with raw-input or browser settings changed only one at a time.
