About mouse latency
Mouse latency is not one number. It is the full chain between button actuation and the response you finally see or feel.
What affects latency
Hardware, connection mode, and the display chain all matter, so a browser page is best used for relative comparison.
How to reduce latency
These suggestions are aimed at daily tuning and troubleshooting so the input chain stays as tight as possible.
Common questions
These answers separate browser-side input response from true end-to-end hardware latency.
