Test your mouse's polling rate (Hz). Polling rate represents how often your mouse reports its position to the computer per second. Higher values mean more precise tracking.

Avg 0 Hz, Max 0 Hz
Polling rate indicates how often your mouse reports its position to the computer, measured in Hz (times per second). Higher polling rates mean more frequent updates and more precise cursor tracking.
For most users, 500Hz is sufficient. Competitive gamers may prefer 1000Hz for slightly faster response times, though the difference is minimal (just 1ms faster than 500Hz).
The difference is small - 1000Hz reports every 1ms while 500Hz reports every 2ms. This 1ms difference is barely noticeable for most users.
Use your mouse's software/driver to adjust the polling rate. Some gaming mice support rates from 125Hz to 1000Hz. Note: Not all mice support high polling rates.
For best results: use a wired mouse, close other programs, and move the mouse continuously during testing. Browser performance may also affect accuracy.
