Mouse Acceleration Test
Move the same physical distance twice: once slowly, once fast. If the counts differ, acceleration is on.

How to Use the Mouse Acceleration Test
With mouse acceleration, a fast swipe moves the cursor further than a slow one over the same distance. That ruins muscle memory in games. This test locks the pointer and counts raw movement for a slow pass and a fast pass. Equal counts mean no acceleration.
- Mark a distance. Use the edge of a mouse pad or a ruler, about 10 cm.
- Do the slow pass. Click Slow pass, move slowly across the distance, click to finish.
- Do the fast pass. Same distance, quick swipe, click.
- Read the difference. Under 8% means no acceleration.
How to Turn Off Mouse Acceleration
- Windows: Settings › Bluetooth & devices › Mouse › Additional mouse settings › Pointer Options › untick "Enhance pointer precision".
- macOS: System Settings › Mouse › Advanced › turn off "Pointer acceleration".
- Linux: set the acceleration profile to "flat" in your desktop settings.
- Mouse software: turn off acceleration in Logitech G HUB, Razer Synapse and others.
Negative Acceleration
If the fast pass gives fewer counts, the sensor is losing tracking at speed. This is called spin-out. Try a different mouse pad, lower the lift-off distance, or use a mouse with a better sensor.
Frequently Asked Questions
Is mouse acceleration bad for gaming?
For aiming, yes. Most players turn it off for consistent muscle memory.
Why is the result different each time?
Hand-moved distances vary a little. Do 3 passes of each.
Do games use raw input?
Many do, which skips Windows acceleration, but mouse software can still add it.
Does it work on Mac?
Yes.
