Polling Rate Test
Measure the movement update rate your browser can observe from a mouse or controller. Compare event delivery, timing consistency and short dips with live charts and repeatable timed sessions.

Choose your device and collection method. Results describe browser-observed events or controller state updates, not direct USB or wireless hardware reports.
MEASUREMENT SETTINGS
Mouse input must move over the tracking surface. Higher-frequency APIs depend on browser support and HTTPS.

Event / timestamp based rate Browser-limited or inconclusive
A 1000Hz hardware device can produce far fewer JavaScript callbacks. A mouseevent is not guaranteed to represent one device poll.

How to Measure Browser-Visible Polling Rate
Start and keep moving
Use continuous brisk mouse movement, or rotate an analog stick throughout controller sampling.
Keep the page visible
Don't change tabs, minimize the browser or stop movement during the session.
Compare multiple runs
Review average, peak, median gap, jitter and consistency before interpreting a result.
04 / MOUSE POLLING GUIDE
How to Test a Gaming Mouse at 125, 500 or 1000 Hz
Place your mouse on a large, consistent surface and move it continuously across the test pad. Choose Automatic for the broadest supported event path, or compare pointermove and mousemove results.
- Confirm the mouse connection and selected mode in its official software.
- Move in smooth loops throughout the timed capture.
- Compare results from the same browser under similar conditions.
- For hardware verification, use the device manufacturer's diagnostics or suitable native tools.
For high-rate mice, browser callback frequency can be substantially lower than physical device polling.

05 / GAMEPAD UPDATE GUIDE
How to Check Controller Update Rate in Your Browser
Press a controller button to make it visible to the browser, choose Controller mode and rotate a stick continuously during the test. The tool records changes to Gamepad API timestamps, not the actual USB or wireless transmission schedule.
- Connect the controller by USB or supported wireless connection.
- Select it from the controller list and start the test.
- Rotate the analog stick throughout the capture period.
- Compare repeated runs without assuming a low browser result means hardware failure.
Controller sampling may be limited by animation-frame cadence, firmware behaviour and browser mapping.

GAMEPAD API / LIVE INPUT
What This Polling Rate Test Actually Measures
Mouse Pointer Events
The tool counts browser-visible mouse movement events. Browsers may align pointermove with display frames or combine multiple input updates.
Raw Pointer Events
pointerrawupdate may expose more frequent movement data on supported HTTPS browsers. It is not universally available or identical to raw USB traffic.
Coalesced Samples
Where exposed, merged pointer events can contain additional samples. These are reported separately from JavaScript callback counts.
Controller Timestamps
Controller mode observes distinct Gamepad API timestamps on animation frames. It cannot read every hardware report between browser frames.
Timing Stability
The interquartile range of observed time gaps describes spread, not guaranteed firmware or radio jitter.
Hardware vs Browser
Nominal 125/250/500/1000/4000/8000 Hz values specify report intervals. An online test cannot certify the actual device setting.
Why Is My Measured Rate Lower Than Expected?
Browser event coalescing
A browser may combine movement into fewer dispatched events. Try raw pointer events if supported.
Mouse movement too slow
Slow or stationary movement produces too few samples. Re-run with steady motion over the testing area.
Controller frame limit
Gamepad state is observed inside requestAnimationFrame. A displayed 60–144 Hz is not proof the controller runs at that native report rate.
Background activity
Busy browser tabs, operating-system scheduling and inactive pages can delay callbacks and skew measurements.
Connection differences
USB, Bluetooth and dedicated wireless connections can differ. Compare modes only with consistent conditions.
Physical device settings
Check the exact mouse or controller software and firmware for an advertised report-rate setting.
Polling Rate Test FAQs
What is polling rate?
It is the rate at which a device reports state to its host, usually stated in hertz. For example, a nominal 1000Hz rate corresponds to a 1ms report interval.
Can an online tool measure my exact mouse hardware Hz?
No. It can measure mouse movement callbacks and available coalesced samples but cannot read USB or Bluetooth report traffic directly.
Why does a 1000Hz mouse show only 60Hz?
The browser may dispatch mouse movement in line with animation frames, or it may have coalesced updates. A low browser result alone does not prove a mouse fault.
Does the tool support 4000Hz or 8000Hz mice?
It can show rates exposed by the browser, but it does not certify 4000Hz or 8000Hz hardware polling. High-rate movement samples may not reach JavaScript individually.
What is pointerrawupdate?
It is a browser Pointer Events interface intended to expose input updates with less delay than ordinary pointermove. Support depends on the browser and secure context.
What does the coalesced option do?
It counts available movement samples embedded in pointer events. The reported sample rate can differ from the callback rate; neither is a raw USB measurement.
Can I test an Xbox or PlayStation controller?
Yes, if the browser exposes the controller through the Gamepad API. Controller mode observes timestamp changes while you move a stick.
Why do I need to keep moving my device?
A static cursor or stick may produce no new movement events or timestamps, so the page has too little data for a useful observation.
Does a higher rate always mean lower gaming input lag?
More frequent hardware reports can reduce report-interval delay, but overall response time also depends on drivers, the game, rendering and display. An online result is not end-to-end latency.
Does this work on phones and tablets?
The page layout is responsive. You need a physical supported mouse or controller for meaningful polling measurements; finger touches are not interpreted as mouse polling.
