Polling Rate Test — Measure Your Mouse Report Rate (Hz)
Move your mouse inside the test area to measure your polling rate in real time. See your Hz readings, track stability, and compare against standard gaming rates.

Note: Browsers typically cap event delivery at ~60-240Hz depending on your display refresh rate. If your mouse supports 1000Hz+, the actual hardware rate may be higher than shown.
Polling Rate Reference

What is Mouse Polling Rate?
Mouse polling rate, measured in Hertz (Hz), refers to how often your mouse reports its position to your computer per second. A polling rate of 1000Hz means your mouse sends 1,000 position updates every second, resulting in a 1 millisecond delay between each report.
Higher polling rates provide smoother, more responsive cursor movement by reducing the time between position updates. This is particularly important in fast-paced gaming scenarios where every millisecond of input delay can affect your performance. Most modern gaming mice support at least 1000Hz, with newer models offering 2000Hz, 4000Hz, or even 8000Hz polling rates.
How Polling Rate Affects Gaming
In competitive gaming, polling rate directly impacts how quickly your aim movements are registered by the game. At 125Hz (8ms delay), your mouse reports its position only 125 times per second, which can create noticeable input lag and choppy cursor movement during fast flick shots.
At 1000Hz (1ms delay), mouse movements feel significantly smoother and more responsive. The difference is most apparent in first-person shooters (FPS) where rapid aim adjustments are crucial. Professional esports players almost universally use 1000Hz or higher polling rates to minimize any potential input delay disadvantage.
However, the perceptible difference diminishes at higher rates. While going from 125Hz to 1000Hz is dramatic, the jump from 1000Hz to 4000Hz offers diminishing returns that most players cannot consistently feel. The benefits of ultra-high polling rates are primarily relevant at very high display refresh rates (240Hz+).
How to Change Your Mouse Polling Rate
Most gaming mice allow you to change the polling rate through their companion software. Here are the common methods:
- Manufacturer Software: Use Razer Synapse, Logitech G Hub, SteelSeries GG, or your mouse brand's software to adjust the polling rate setting. It is typically found under performance or sensitivity settings.
- On-Mouse Controls: Some mice have a physical button on the bottom that cycles through polling rate options. Check your mouse's manual for button combinations.
- DIP Switches: Certain mice use DIP switches on the underside to set polling rate. Each switch combination corresponds to a different rate.
- Onboard Memory: Newer mice with onboard profiles can store polling rate settings without needing software running.
After changing your polling rate, use this tool to verify the new setting is active. Keep in mind that browser-based measurement has limitations and may not fully reflect rates above ~240Hz.
Polling Rate vs DPI
Polling rate and DPI (dots per inch) are two separate mouse specifications that are often confused. DPI determines how far your cursor moves relative to physical mouse movement — higher DPI means more cursor distance per inch of mouse movement. Polling rate determines how frequently those position updates are sent to your PC.
Think of DPI as the "resolution" of your mouse sensor and polling rate as the "refresh rate" of communication. A high-DPI mouse with a low polling rate will move the cursor far with each report but update infrequently. A low-DPI mouse with a high polling rate will send frequent updates but move less distance per report.
For optimal gaming performance, you want both: a DPI setting that matches your sensitivity preference and a polling rate of at least 1000Hz for responsive input. Most competitive FPS players use 400-1600 DPI with 1000Hz polling rate.
Frequently Asked Questions
Most modern gaming mice support 1000Hz polling. Budget mice typically default to 125Hz. Check your mouse manufacturer's specifications or software for the exact supported rates. This tool can help verify your current active polling rate, though browser limitations may cap the reported value at around 60-240Hz.
Browsers limit the rate at which pointer events are delivered, typically capping at your display's refresh rate (60-240Hz). This is a browser limitation, not a mouse issue. Your actual hardware polling rate may be much higher. For accurate high-frequency measurement, use a native desktop application like MouseTester by microe.
Yes, 1000Hz (1ms delay) is more than sufficient for virtually all gaming scenarios. It's the standard for competitive esports. While 4000Hz and 8000Hz mice exist, the real-world benefit over 1000Hz is minimal for most players. Focus on a reliable sensor and comfortable shape before chasing higher polling rates.
Yes, higher polling rates do increase CPU usage slightly because the processor must handle more USB interrupt requests per second. At 1000Hz, the impact is negligible on modern systems. At 4000Hz or 8000Hz, you may notice a small increase in CPU usage (typically 1-3%), which could matter on older or resource-constrained systems.
Absolutely. A high polling rate mouse works perfectly for everyday tasks, web browsing, and productivity. You might notice slightly smoother cursor movement. There's no downside to using a 1000Hz mouse for general use, though the battery life of wireless mice may be reduced at higher polling rates.
Polling rate (Hz) is how often your mouse reports its position per second. Response time (ms) is the delay between each report and equals 1000 divided by the polling rate. For example, 1000Hz equals 1ms response time, 500Hz equals 2ms, and 125Hz equals 8ms. They are inverse measurements of the same concept.
