Frequently Asked Questions (Mouse Click Latency & Response Time Diagnostic Tool)
10-Item Technical FAQ & PointerEvent Telemetry Troubleshooting
What is mouse click latency?
Click latency is the delay between physical switch actuation and the computer registering the click signal.
What is good click latency for gaming mice?
Top gaming mice achieve sub-1ms to 3ms click latency; office mice range from 8ms to 20ms.
How is online click latency measured?
Measures sub-millisecond deltas between physical event dispatch and browser DOM rendering frames using `performance.now()`.
What causes high mouse click latency?
Causes include high MCU debounce delay, low USB polling rate (125Hz), wireless signal interference, or OS DPC latency.
How do optical mouse switches reduce click latency?
Optical switches trigger instantaneously via light beam disruption, bypassing 2-5ms mechanical debounce delay.
Does monitor refresh rate impact perceived click latency?
Yes, higher refresh rate displays (240Hz/360Hz) render visual click feedback faster, reducing click-to-photon latency.
What is click debouncing and why does it add latency?
Firmware waits 2-8ms for metal leaf vibration to settle before confirming click registration, adding hardware delay.
Do wireless gaming mice have higher click latency than wired?
Modern 2.4GHz wireless gaming mice achieve click latency equal to or lower than standard wired USB mice.
How do I lower my mouse click latency?
Set mouse polling rate to 1000Hz+, lower software debounce time to lowest stable setting (e.g. 2ms), or use optical switches.
How do I export my click latency benchmark logs?
