Why Mouse Polling Rate Is Vital for High-Refresh Gaming
Mouse polling rate determines how many times per second your optical mouse sensor reports cursor coordinates to the operating system.

Mouse Polling Rate Ratings
1000Hz – 8000Hz (0.125ms – 1ms)
Esports standard. Ultra-smooth tracking for 240Hz+ monitors.
500Hz (2ms)
Standard gaming rate. Great balance of performance and CPU usage.
125Hz (8ms)
Office mouse default. High input delay in fast shooters.
How to Get Started
Just three steps to run a complete controller test and understand your controller's health status.
01
Connect Controller
Connect your controller to your computer via USB cable or Bluetooth. If the browser doesn't respond, press any button on the controller to activate the connection.
02
Button Detection
Press each button in the visual interface and confirm the corresponding area lights up on screen. This helps troubleshoot unresponsive or double-clicking buttons.
03
Sticks & Vibration
Rotate the sticks to check linearity and drift issues; click the vibration test button to feel if the left and right motor feedback is working properly.
What would you like to do next?
Select a diagnostic calibration suite, deadzone analyzer, or high-frequency overclock tool.

Repair & Calibration
Calibrate zero-point offsets or follow step-by-step repair guides.
Optimize
Game Deadzones
Calculate exact radial vs axial deadzone overlays for Fortnite, Apex, & COD.
Telemetry
Overclock & Circularity
Verify true hardware polling Hz stability and statistical circularity grades.
Frequently Asked Questions
Everything you need to know about testing your controller.
How do I test my mouse polling rate (Hz)?
Move your mouse cursor rapidly inside the dashed target area above. The tool measures your mouse sensor's report interval in milliseconds and displays real-time Hz.
Is 1000Hz, 4000Hz, or 8000Hz better for gaming?
Higher polling rates reduce cursor jitter and input delay. A 1000Hz mouse updates every 1.0ms, while an 8000Hz (8KHz) mouse updates every 0.125ms for ultra-smooth tracking on high-refresh monitors (240Hz+).
Why is my mouse polling rate lower than advertised?
Ensure your mouse is plugged into a USB 3.0/3.1 port, close background CPU-heavy applications, and enable maximum polling rate in your mouse driver software (Razer Synapse, Logitech G HUB).
How this test works & its limits
- This test reads your controller through the browser's standard Gamepad API — no drivers, no installs, nothing leaves your device.
- Readings depend on connection mode: Bluetooth reports at lower rates than USB. Compare like-for-like (wired vs wired).
- We measure the input reaching the browser — display lag and game-engine queues are outside this test's view.
- A clean reading now does not guarantee no drift in-game: deadzones differ per game, and wear develops over time. Use the Drift Timeline to track yours.
- This is a diagnostic, not a hardware-lab certification. For repair or RMA decisions, confirm with a second run or second tool.
