Mouse Polling Rate Test
Measure real-time mouse reporting frequency (Hz), peak update rate, interval jitter, and latency distribution directly in your browser. Works with 125Hz, 500Hz, 1000Hz, 4000Hz, and 8000Hz gaming mice. No install required — 100% client-side.
Mouse polling rate is the frequency—measured in Hertz (Hz)—at which your mouse reports its position and clicks to your computer. A 1000 Hz mouse sends updates every 1 millisecond, reducing input latency to under 1 ms. Common gaming rates include 500 Hz (2 ms), 1000 Hz (1 ms), 4000 Hz (0.25 ms), and 8000 Hz (0.125 ms).

ACCURACY & METHODOLOGY
This page counts browser-visible movement samples, including coalesced samples when available. It cannot verify every USB poll or diagnose a faulty mouse. A low reading alone does not establish a hardware problem.
Shows the effective rate your browser receives after OS and USB processing.
When supported, raw pointer updates reduce browser throttling and compositor delays.
Collect at least 3 seconds of continuous movement and 100 samples. Keep moving through the end of the test; pauses remain part of the result.
What Is Mouse Polling Rate?
Mouse polling rate determines how frequently your mouse microcontroller interrogates its optical or laser sensor and transmits the resulting movement packet to your operating system via the USB bus or 2.4 GHz wireless transceiver. Measured in Hertz (Hz), this value denotes cycles per second.
Unlike monitor refresh rates (which dictate how often frames are drawn to your display), polling rate dictates how fresh the cursor coordinate data is before the game engine computes the next frame. Standard office mice operate at 125 Hz (reporting every 8 milliseconds), while competitive esports mice standardly run at 1000 Hz (every 1 millisecond) or up to 8000 Hz (every 0.125 milliseconds) to virtually eliminate input latency.
It is critical to distinguish polling rate from DPI (dots per inch) and in-game sensitivity. DPI governs how many pixels the cursor traverses per inch of physical movement, whereas polling rate governs the communication frequency between the mouse and your CPU.
How to Use the Mouse Polling Rate Test
Choose a timed benchmark duration (8 seconds is recommended for statistical stability) or run a continuous live frequency test.
Click the 'Start Benchmark' button or immediately begin sweeping your mouse across the interactive diagnostic test pad.
Optical sensors only transmit USB packets when motion is registered. Move your mouse swiftly and continuously in circles across the test area to fully saturate every USB polling cycle.
Keep the cursor moving within the test container without banging into screen edges, which could temporarily interrupt mouse movement deltas.
Watch the live frequency gauge, current Hz readings, peak update rate, and interval timing jitter graph update in real time.
Examine your average Hz, maximum observed report rate, standard deviation jitter score, and interval histogram after the timer expires.
How to Read Your Results & Performance Benchmarks
Compare your observed diagnostic measurements against verified hardware standards.
| Polling Rate | Interval (ms) | Hardware Class | Gaming Benchmark Assessment |
|---|---|---|---|
| 125 Hz | 8.0 ms | Standard Office / Bluetooth | Noticeable input delay; unsuited for fast-paced competitive esports. |
| 500 Hz | 2.0 ms | Entry-Level Gaming | Smooth, responsive tracking with minimal CPU interrupt overhead. |
| 1000 Hz | 1.0 ms | Esports Competitive Benchmark | The tournament standard for CS2, Valorant, and Apex Legends. |
| 2000 Hz | 0.5 ms | High-Performance Gaming | Measurable latency reduction; noticeable on 144 Hz to 240 Hz displays. |
| 4000 Hz | 0.25 ms | Ultra High-Speed Gaming | Extreme smoothness on 240 Hz+ monitors; requires modern multi-core CPU. |
| 8000 Hz | 0.125 ms | Flagship Enthusiast Tier | Absolute minimum input lag (0.125 ms); high CPU interrupt load during rapid movement. |
Common Polling Rate Issues and How to Fix Them
Cause: Generic Windows HID drivers, Bluetooth connection mode (which caps at 125-133 Hz), or power-saving profiles in vendor software.
Cause: Moving the mouse too slowly to saturate USB intervals, or browser event coalescing during compositor vsync periods.
Cause: USB hub contention, connecting the receiver to USB 3.0 ports with 2.4 GHz RF interference, or CPU throttling.
Cause: Game engines not designed for high report density, older CPUs overloaded by interrupt requests, or lack of raw input buffering.
This online test evaluates pointer events dispatched via the browser's high-resolution Pointer Events API (pointerrawupdate and pointermove) using monotonic performance.now() timestamps. While excellent for diagnosing hardware configuration errors, cable faults, and nominal operating modes, browser event delivery is subject to operating system compositor scheduling, JavaScript thread availability, and display refresh coalescing. For mission-critical hardware certification, measurements should be correlated with dedicated kernel-level tools or USB protocol analyzers.
