The mouse polling rate test captures raw event intervals via window pointermove + getCoalescedEvents, then computes estimated Hz from trimmed average. Includes 3 test slots, deviation analysis, and frame drop status.

Features

Precise getCoalescedEvents() sampling.
Fixed 10-second test duration.
Per-second independent Hz tracking.
Automatic deviation marking.
Average/min/max summary.

  • USB port speed comparison.

FAQ

What is mouse polling rate?

Polling rate is how many times per second your mouse reports to the PC. 125Hz=8ms, 1000Hz=1ms.

Why 300Hz on a 1000Hz mouse?

Could be USB bandwidth limits, wireless interference, or high system load. Try a USB3.0 port.
