How do I check my mouse polling rate online?

Go to InputTest.online/mouse-polling-rate and move your mouse continuously inside the interactive test arena. The tool tracks every mousemove event with microsecond precision, calculating your real-time report rate in Hertz (Hz), peak Hz, and average latency.

What is a good polling rate for gaming?

1000Hz (1 millisecond delay) is the competitive esports gold standard for first-person shooters like CS2, Valorant, and Apex Legends. Enthusiast mice now support 4000Hz (0.25ms) and 8000Hz (0.125ms), while casual office mice typically run at 125Hz (8ms).

Why is my 1000Hz mouse only showing 500Hz or fluctuating?

Mouse polling rate is movement-dependent. If you move your mouse slowly or at low DPI, the sensor does not generate enough movement packets to saturate 1000Hz. Move your mouse fast in circular motions across the test box, ensure your mouse software (Razer Synapse, Logitech G HUB) is set to 1000Hz, and plug directly into a rear motherboard USB 3.0 port.

Does 4000Hz or 8000Hz mouse polling rate cause CPU lag in games?

Yes, high polling rates like 4000Hz and 8000Hz generate 4 to 8 times more CPU interrupts per second. On older 4-core or 6-core CPUs, this can cause frame drops and stuttering in games. A modern multi-threaded CPU (Intel Core i7/i9 or AMD Ryzen 7/9) is recommended for 4000Hz+ polling.

Troubleshooting: Why Isn't My Mouse Reaching 1000Hz or 4000Hz?

1. Low DPI or Slow Mouse Movement

To report 1000 times per second, your mouse sensor must physically register movement counts. If your DPI is set to 400 or you move slowly, the mouse will only report 200–500Hz. Move rapidly in large circles across the test arena.

2. Unpowered USB Hubs & Front Ports

Front PC case USB ports and unpowered desk USB hubs share bus bandwidth with other devices, causing packet throttling. Always plug your gaming mouse receiver directly into a rear motherboard USB 3.0+ port.

3. Mouse Driver & Polling Rate Software

Check your manufacturer utility (Logitech G HUB, Razer Synapse, SteelSeries GG, Wootility). Verify that the Report Rate profile is explicitly set to 1000Hz (or 4000Hz/8000Hz) rather than 500Hz power-saving mode.

4. 2.4GHz Wireless Signal Interference

If your wireless receiver is behind a metal computer chassis or next to a Wi-Fi router, packet drops will cause Hz instability. Use the included USB extender cable to place the wireless dongle within 20cm of your mousepad.

Frequently Asked Questions

How accurate is an online browser polling rate test?

InputTest uses the browser's high-resolution `event.timeStamp` API (microsecond precision) coupled with `requestAnimationFrame`. For rates up to 1000Hz, browser tests match dedicated desktop profilers like MouseRate with 99%+ accuracy.

Can I feel the difference between 1000Hz and 4000Hz?

On standard 60Hz or 144Hz monitors, the difference between 1000Hz (1ms) and 4000Hz (0.25ms) is barely noticeable. However, on high-refresh 240Hz, 360Hz, or 540Hz OLED gaming displays, fast flick tracking feels visibly smoother.

Does higher polling rate drain wireless mouse battery faster?

Yes. Running a wireless mouse at 4000Hz or 8000Hz can reduce battery life by 50% to 75% compared to 1000Hz, because the wireless radio sends 4x to 8x more data packets every second.
