Mouse Acceleration Detector
Find out if your OS mouse acceleration is active. Move slowly then quickly — we analyze your cursor's nonlinearity.
Frequently Asked Questions
What is mouse acceleration?
A setting that makes the cursor move further when you move the mouse faster. It can make precise aiming harder because your muscle memory becomes inconsistent.
How does this test detect it?
You move your mouse slowly then quickly. We compare how nonlinear your cursor speed is between the two phases. If fast movement produces disproportionately higher speed variance, acceleration is likely active.
Is acceleration always bad?
For gaming (FPS, RTS), turning it off is recommended for consistent aim. For everyday desktop use, it is a personal preference.
