How to Use This Tool

STEP 1
Move Mouse Continuously
Place your cursor in the dashed box and move the mouse rapidly in circles.
STEP 2
Inspect Peak Hz
Your mouse report frequency will snap to standard tiers: 125Hz (8ms), 500Hz (2ms), 1000Hz (1ms), or 4000Hz/8000Hz.
STEP 3
Measure Physical DPI
Use the ruler test below to verify that your configured mouse DPI (e.g. 800 or 1600 DPI) matches physical travel.

Frequently Asked Questions

What is mouse polling rate?
Polling rate (measured in Hz) indicates how many times per second your mouse reports its position back to the computer.
Does 1000Hz or 8000Hz polling rate improve gaming?
Yes. A 1000Hz mouse updates every 1ms compared to 8ms on a 125Hz office mouse, resulting in noticeably snappier crosshair aim and reduced input lag.
Why is my 1000Hz mouse only showing 500Hz?
Ensure you move your mouse quickly. Optical sensors only transmit packet updates when physical movement occurs. Also verify polling rate settings in your mouse manufacturer software (Razer Synapse, Logitech G Hub).
What causes high polling rate mouse stuttering in games?
Polling rates like 4000Hz and 8000Hz transmit thousands of interrupts per second, which requires a fast multi-core CPU and high Windows timer resolution.
