What Is Mouse Polling Rate?
Polling rate is how often per second your mouse reports its position to your computer, measured in Hertz (Hz). A 125Hz mouse reports 125 times per second, while a 1000Hz "gaming" mouse reports 1000 times per second - a higher rate generally means lower input lag and smoother cursor tracking, which matters most in fast-paced games.
How to Use This Test
- Move your mouse quickly and continuously inside the gray box above.
- Keep moving for a few seconds to gather enough samples.
- Read your estimated polling rate and average interval between reports.
How It Works
This tool listens to pointermove events and measures the time gap between each one while
your mouse is actively moving. Browsers can sometimes cap or batch how often movement events are delivered
to JavaScript, so this measurement reflects what your browser can observe - dedicated hardware polling-rate
testers outside the browser may show a slightly higher number for very high-end mice.
Understanding Your Results
| Measured Rate | Typical Mouse Type |
|---|---|
| ~125Hz | Standard office/budget mice (default USB polling) |
| ~500Hz | Mid-range gaming mice |
| ~1000Hz | Gaming mice with polling rate set to maximum |
If your gaming mouse shows a lower rate than expected, check its manufacturer software - many mice let you manually set the polling rate, and it doesn't always default to the maximum.
Benefits
- Confirms your mouse and its software settings are delivering the polling rate you expect.
- Helps troubleshoot input lag complaints during competitive gaming.
Common Mistakes to Avoid
- Moving too slowly - quick, continuous movement gives more reliable samples.
- Testing on a laggy system - heavy background CPU load can affect the measurement.
Frequently Asked Questions
Does higher polling rate always feel better?
Higher polling rates reduce input lag and can feel smoother, but the difference becomes harder to notice above 500–1000Hz for most players, and very high rates can slightly increase CPU usage.
Why is my measured rate lower than my mouse's rated spec?
Browser-based measurement can be slightly conservative compared to dedicated hardware tools, and your mouse's software may not be set to its maximum polling rate by default.
Does polling rate affect DPI?
No, they're separate settings. DPI controls cursor sensitivity per inch of physical movement, while polling rate controls how often position updates are sent to your computer.
