Pointer event estimate
Estimate how often your browser receives mouse movement events.
Browser-based estimate
Keep moving for a few seconds to collect pointer events.
This is an estimate. Browser scheduling, operating system load, display refresh rate, USB connection, and hardware can affect the result.
This tool estimates the rate from pointer events; it is not a laboratory measurement. Operating-system scheduling, browser behavior, display refresh, system load, and the connection itself influence the number shown.
