Mouse Polling Rate Test — Free Online Hz Checker
Instantly verify your mouse’s true polling rate in Hz. Works with every brand from Logitech to Razer to Pulsar — up to 8000Hz. No download, no signup, runs entirely in your browser.
Start the test by moving your mouse in the area above. Once you have at least 200 samples, we’ll automatically interpret your polling rate here.
What is Mouse Polling Rate?
Mouse polling rate is the frequency, measured in Hertz (Hz), at which your mouse sends position and click data to your computer. A 1000Hz mouse reports 1000 times every second — once per millisecond. A 125Hz office mouse reports only 125 times per second, with an 8ms gap between updates.
For competitive gamers, this gap is everything. The lower your polling rate, the higher the chance your computer registers your movement after the moment you actually made it. Multiply that across thousands of micro-movements in an FPS match and the difference becomes real.
How to Test Your Mouse Polling Rate Accurately
Follow these four steps for the most accurate result from the tester above:
- Plug your mouse into a fast USB port — USB 2.0 or 3.0 (not a hub if possible). USB 1.1 ports cap at 125Hz.
- Set your mouse to the rate you want to verify in its software (Razer Synapse, Logitech G HUB, Corsair iCUE, etc.) before testing.
- Close unnecessary background apps — RGB software, voice chats, and downloads can throttle inputs.
- Move your mouse in tight, consistent circles inside the test area for at least 5–10 seconds. Faster, more continuous movement gives more samples and a more accurate average.
Continuous circular motion produces a steady stream of mouse events. Linear movements or jerky motions can briefly stop input, creating gaps that throw off the average. Small, fast circles maximize the sample rate.
How to Read Your Polling Rate Test Results
The tester gives you four numbers. Here’s what each means:
| Metric | What it Means | What’s Normal |
|---|---|---|
| Current Hz | Live rate calculated from the last ~30 events | Should hover near your set rate |
| Average Hz | Mean polling rate across the whole test | Within 90–100% of your set rate |
| Peak Hz | Highest single-instant rate detected | Often slightly above your set rate (normal) |
| Minimum Hz | Lowest rate during the test | If much lower than average, you have instability |
What “Good” Results Look Like
For a healthy 1000Hz mouse, you should see average between 920–1000Hz, peak around 1000–1080Hz, and minimum no lower than 800Hz. Browsers tend to read 5–10% lower than vendor software due to JavaScript event handling — this is normal.
What Polling Rate is Best for Gaming?
The honest answer: 1000Hz. Here’s why, broken down by use case:
Competitive FPS (CS2, Valorant, Apex)
1000Hz. Every major pro plays at this rate. 8000Hz is marketing — most pros don’t bother.
Casual Gaming & MOBAs
500Hz is plenty. The 1ms vs 2ms gap is invisible outside of twitch shooters.
Productivity / Office
125Hz is the default and is perfectly fine. Going higher just uses more CPU.
4K / Creative Work
500–1000Hz. Smoother cursor tracking helps in Photoshop, video editing, CAD.
How to Change Your Mouse Polling Rate
Most modern mice let you change polling rate through vendor software. Quick paths for the major brands:
- Logitech: Open Logitech G HUB → Select mouse → Sensitivity (DPI) tab → Report Rate.
- Razer: Open Razer Synapse → Mouse → Performance tab → Polling Rate dropdown.
- Corsair: Open iCUE → Device → Performance → Polling Rate slider.
- SteelSeries: Open GG / Engine → Mouse → Settings → Report Rate.
- Glorious / Pulsar / Endgame Gear: Vendor-specific software, or DPI/polling rate buttons under the mouse.
After changing, re-test with our tool to confirm the new rate is live.
Troubleshooting Low or Fluctuating Polling Rate
Test shows ~125Hz when I set 1000Hz
Most likely a USB issue. Try a different USB port (use USB 2.0+ direct on the motherboard, not a hub). Update your mouse firmware. Restart your PC after changing the rate in vendor software.
Hz fluctuates wildly (e.g. 200–1100Hz)
Causes: inconsistent movement, USB power saving, background CPU load. Disable USB selective suspend in Power Options. Move continuously in tight circles. Close RGB software during the test.
Maximum doesn’t reach the advertised rate
Browser timing isn’t perfect — a “1000Hz” reading of 920Hz is fine. If you’re well below (e.g. 600Hz), check your mouse driver, USB cable, and whether your mouse is set to wireless 2.4GHz vs Bluetooth (Bluetooth caps at 125Hz on most models).
Mouse Polling Rate Test FAQs
How do I test my mouse polling rate?
Open this page, click into the test area above, then move your mouse rapidly in small circles for 5–10 seconds. The tool measures the time between mouse events using performance.now() and displays your polling rate in Hz in real time.
What is a good mouse polling rate?
1000Hz is the gold standard for competitive gaming, delivering 1ms response time. 500Hz is excellent for casual gaming. 125Hz is fine for office work. Ultra-high rates (4000Hz, 8000Hz) offer marginal benefits and use more CPU.
Why is my mouse showing only 125Hz?
Your mouse may be set to 125Hz in its driver software, plugged into a slow USB 1.1 port, or limited by the mouse’s hardware. Open your mouse software (Razer Synapse, Logitech G HUB, etc.) and increase the polling rate.
Can the browser test measure 8000Hz mice?
Yes. We use the getCoalescedEvents() API which captures every input event the browser receives, even at 8000Hz. Note that some browsers cap event delivery to the screen refresh rate; for absolute accuracy on 4000Hz+ mice, also verify with vendor software.
Is 500Hz or 1000Hz better?
1000Hz halves response time from 2ms to 1ms. In competitive FPS, you’ll notice marginally smoother aim tracking. Outside of twitch games, you won’t. Pick 1000Hz if your CPU isn’t bottlenecked; 500Hz if you’re CPU-limited.
Does polling rate affect aim?
Indirectly, yes. A higher polling rate means smoother cursor updates and reduced input delay, which makes flick shots and micro-corrections feel more responsive. It does not change your DPI or sensitivity — only how often your movement is reported.
Wireless vs wired polling rate test — different?
Modern 2.4GHz wireless gaming mice (Logitech Lightspeed, Razer HyperSpeed) hit the same polling rates as wired (1000Hz+). Bluetooth mice are capped at ~125Hz due to the protocol. Always test with the actual connection you use for gaming.
