Frequently Asked Questions
How do I check my keyboard polling rate?
Select the Keyboard tab on this keyboard polling rate test and tap any key repeatedly. The tool measures how many distinct key report signals register per second.
What is the best polling rate for gaming?
The best polling rate for mouse and keyboard gaming is 1000Hz, delivering responsive 1ms latency without unnecessary CPU overhead.
Does a higher polling rate feel different?
Moving from 125Hz to 1000Hz yields visibly smoother tracking and snappier crosshair aim. Upgrades beyond 1000Hz to 4000Hz or 8000Hz offer subtle improvements on high-refresh 240Hz+ monitors.
Why does the browser show a lower Hz than my mouse supports?
Web browsers run through the operating system compositor and display refresh rate, which can bundle pointer events. Dedicated hardware software shows the raw internal sensor frequency.
