Mouse Polling Rate Test

Your mouse can only aim as fast as it can talk. Every time you move it, it sends a position report to your computer — and how many of those reports it sends per second is its polling rate, measured in hertz (Hz). This mouse polling rate test measures the rate your mouse is actually running at right now, live in your browser, with no download and nothing to install. Run it on Speed Test UK whenever you change a mouse, a USB port or a setting, and you will know within seconds whether the number on the box matches the number on your desk.

That gap between the box and reality is exactly why this test exists. Plenty of gaming mice ship set to 1000 Hz even when the hardware supports 4000 or 8000 Hz. Wireless mice quietly drop their rate to save battery. A mouse plugged into a cheap USB hub or the wrong port can be throttled without any warning. The specification tells you what the mouse can do; the test tells you what it is doing.

How to Run the Mouse Polling Rate Test

The test counts the movement reports your browser receives while you move the mouse. A mouse sends nothing when it sits still, so the whole trick is steady, fast movement. Follow these steps for a reading you can trust:

• Step 1: Close anything that might stutter your browser — heavy tabs, video streams and downloads all compete for attention.
• Step 2: Click Start test, then move your mouse in big, fast circles inside the test box. Do not stop, pause or lift the mouse.
• Step 3: Keep swirling for at least five to ten seconds. Watch the graph: a healthy mouse holds a fairly steady line rather than swinging wildly up and down.
• Step 4: Read the three numbers. Current Hz is what your mouse is doing this moment, Average Hz is the overall rate for the run, and Peak Hz is the highest short burst it reached.
• Step 5: Click Stop to see your verdict, including the closest standard polling rate. Then change one thing — a different USB port, a wired connection, a setting in your mouse software — and run it again to compare.

One warning before you start: slow or gentle movement gives a low reading that means nothing. A mouse reports when it moves, so a lazy drift across the pad might only trigger a handful of reports per second. Fast circles are not a gimmick; they are how you make the mouse report as often as it possibly can.

What Is Polling Rate, in Plain English?

Polling rate is simply how often your mouse checks in. At 125 Hz, it reports its position 125 times a second — once every 8 milliseconds. At 1000 Hz, it reports every 1 millisecond. At 8000 Hz, every 0.125 milliseconds. The higher the rate, the fresher the position your computer is working from, and the smaller the delay between your hand moving and the cursor (or crosshair) responding.

It helps to think of it like a flipbook. At 125 pages a second the animation is recognisably smooth but a little steppy under fast motion. At 1000 pages it looks continuous. At 8000 pages the individual pages blur into something most people cannot distinguish from reality — which is the honest summary of high polling rates: the jump from 125 to 1000 Hz is dramatic, the jump from 1000 to 8000 Hz is real but subtle, and it only shows itself on high-refresh monitors in fast games.

Polling rate is not the same as DPI. DPI (or CPI) is how far the cursor travels for each inch the mouse moves — sensitivity, in other words. Polling rate is how often the mouse reports. If you are setting up a gaming mouse, sort polling first, then fine-tune sensitivity with our mouse DPI calculator.

Polling Rate Benchmarks: 125 Hz to 8000 Hz Explained

Mouse polling rates come in standard steps. The test above snaps your average to the nearest standard rate so you can compare like with like. Here is what each step means in practice:

Notice the shape of those numbers: each doubling halves a delay that was already small. Going from 8 ms to 1 ms removes 7 ms of lag — easy to feel. Going from 1 ms to 0.125 ms removes less than a millisecond — very hard to feel, and swamped by every other delay in the chain: your monitor, the game engine and your own reaction time. If you want to know how large your personal delay is, take our reaction time test — most people measure 200–300 ms, which puts a 1 ms mouse report in proper perspective.

Why Your Result Might Be Lower Than the Box Says

A lower-than-expected reading is common and usually has a boring explanation. Work through this list before concluding the mouse is faulty:

Your browser may be the limit, not the mouse

This test counts the movement reports your browser receives, and browsers differ. Chrome and Edge on Windows can hand over “coalesced” events — the raw, individual reports bundled inside each browser event — so high polling rates can register properly. Some other browsers merge mouse movement to match your screen’s refresh rate, capping the reading near 60, 120 or 144 Hz no matter how fast the mouse polls. The underlying mechanism is documented in Mozilla’s MDN reference for coalesced pointer events, if you want the technical detail. If your result lands suspiciously close to your monitor’s refresh rate, that is probably what is happening. Test in Chrome or Edge before blaming the hardware.

The mouse is still on its shipping setting

Many 4000 Hz and 8000 Hz mice leave the factory set to 1000 Hz. The higher rates are unlocked in the maker’s software — Logitech G HUB, Razer Synapse, Corsair iCUE, SteelSeries GG or the brand’s web-based driver. Open it, find the polling or report rate setting, raise it, and test again.

Wireless mode is saving battery

Bluetooth is the biggest offender: it typically caps out around 125 Hz. A 2.4 GHz USB receiver can usually run the mouse’s full rate, but some mice drop to 500 Hz or lower on battery-saving profiles. Test with the 2.4 GHz receiver plugged in, close to the mouse, and then test wired if your mouse supports a cable — the difference tells you which link is limiting you.

The USB port or hub is in the way

High-polling receivers want a direct motherboard port, ideally a rear USB port, not a front-panel port, an unpowered hub or a KVM switch shared with three other devices. High polling rates are also the first thing to suffer on a congested USB bus. Move the receiver, retest, and watch the graph settle.

You simply were not moving fast enough

It bears repeating: no movement, no reports. Slow, careful movements produce a low, meaningless number. Fast circles, every time.

Does a Higher Polling Rate Actually Help?

Up to a point, yes — and it is worth being precise about where that point is. A higher polling rate reduces one specific delay: the wait for the next mouse report. It also makes cursor movement smoother at speed, because the positions your computer receives are closer together in time, which matters most on high-refresh monitors where each frame lasts only a few milliseconds.

What it does not fix is everything else. Total aim delay includes your reaction time (usually 200 ms or more), the mouse’s internal processing and click latency, USB and operating system handling, the game’s tick and frame rate, and your monitor’s response. Polling rate is one slice of that chain. This is why serious players pair mouse setup with click testing — our click speed test measures the other half of the equation, how fast you can actually actuate the button when it matters.

There are costs, too. Higher polling rates ask more of your CPU, because the computer processes thousands of extra interrupts a second; on older machines an 8000 Hz mouse can cause frame-time stutters in some games — the cure performing worse than the disease. Even Razer, whose HyperPolling technology page makes the case for 8000 Hz, notes that the mouse needs a native USB port rather than a hub and a PC able to process the reports. Wireless battery life falls sharply at high rates as well. The pragmatic advice: run 1000 Hz unless you have a modern PC, a 240 Hz or faster monitor and a competitive reason to go higher, and always compare how the game feels, not just how the graph looks.

Frequently Asked Questions

What is a good polling rate for gaming?

1000 Hz is the sensible target for most players: a report every millisecond, supported by virtually every gaming mouse and game, with a modest CPU cost. 500 Hz is fine for casual and slower-paced games. Rates of 4000–8000 Hz are for competitive players on high-refresh monitors; the improvement is real but small, and 125 Hz is best left to office work.

Why does my 8000 Hz mouse only show 1000 Hz?

Usually one of three reasons: it is still on its factory setting and needs the higher rate enabled in the maker’s software; the high-polling receiver is not being used or is plugged into a hub; or your browser is merging movement events so the extra reports never reach the test. Enable the setting, plug the receiver directly into a rear USB port, test in Chrome or Edge, and check the maker’s software readout as a cross-reference.

Is this browser test as accurate as desktop software?

It is accurate about what it measures: the reports your browser receives, counted with high-resolution timestamps, including coalesced raw events where the browser provides them. Desktop tools read the USB stream more directly and are the better final check. If the browser test and the maker’s software disagree, believe the software for the hardware figure — and treat the browser figure as what web games and apps actually get.

Does polling rate affect battery life?

Yes, significantly on wireless mice. Reporting 1000 times a second keeps the radio and sensor busy; reporting 8000 times a second keeps them very busy. Many wireless mice offer separate rates for wired and wireless modes for exactly this reason. If you play plugged in or charge nightly, it barely matters; if you need a week of battery, 500–1000 Hz is the wiser setting.

Can I change my mouse’s polling rate?

On gaming mice, yes — in the manufacturer’s software (G HUB, Synapse, iCUE, GG and similar), sometimes with an onboard button combination or a switch underneath. On basic office mice, generally no: the rate is fixed by the hardware, usually at 125 Hz. Changing the Windows pointer speed setting does not change polling rate; that only scales how far the cursor moves.

Why does my polling rate graph jump around?

Some variation is normal — your hand does not move at a constant speed, and the rate follows it. Big, regular drops to near zero suggest the movement paused (even briefly), the mouse lifted, or the connection struggled: try a direct USB port, move the wireless receiver closer, and test on a clean, matte mouse pad. A wildly unstable graph on a wired mouse, tested on a direct port, is worth raising with the manufacturer.

Test Your Mouse, Then Trust Your Settings

Polling rate is one of those settings everyone quotes and hardly anyone verifies. Now you can: run the test, note the average and how steady the graph looks, and change one variable at a time — port, connection type, software setting — until the number matches the mouse you paid for. When you are happy with the hardware side, head back to the Speed Test UK homepage to check the connection side, and make sure your broadband is not the slowest link in your setup.
