About Mouse Latency
Input lag is key to gaming and work performance. This tool helps you quantify it.
Neural Response
Time from eye to brain to finger. Human average is 200-250ms.
Device Latency
Time from click to signal report. Wired is usually faster, high polling rate helps.
System Latency
Time from render to display. High refresh rate monitors reduce visual latency.
Factors Affecting Latency
Connection
Wired vs Wireless. Top tier wireless is now as fast as wired.
Polling Rate
1000Hz = 1ms interval. Higher rate reduces input lag.
Monitor
High refresh rate (144Hz+) allows you to see changes faster.
Switches
Optical switches eliminate debounce delay, triggering faster.
How to Reduce Latency?
Use Fullscreen mode in games to avoid compositor lag.
Disable V-Sync, use G-Sync/FreeSync instead.
Ensure mouse polling rate is set to max (1000Hz+).
Use native DPI steps to avoid interpolation.
Stay focused and rested. Fatigue increases reaction time.
Upgrade hardware: High refresh monitor and low latency mouse are key.
FAQ
Q.Is this accurate?
This measures event processing delay from system to browser. It's a relative metric for comparing different mice or systems.
Q.What is fast?
<200ms is excellent. Normal is 200-300ms. Pure hardware latency is 0.5-15ms.
Q.Why results vary?
Human attention varies, plus monitor refresh randomness (e.g. 60Hz = 16ms variance). 20-30ms fluctuation is normal.

Click latency tests measure how quickly your system processes mouse input. Lower latency means more responsive feel.
