Mouse Acceleration Test
Swipe across the pad slowly, then swipe the same physical distance fast. If the pixel distances differ, acceleration is being applied somewhere in your stack.
Capture two swipes of the SAME physical distance: one slow (about 2 seconds) and one fast (under 0.5 seconds). A sensor without acceleration will report the same pixel distance for both. Ratios above 1.05 mean acceleration is being applied.
Step 1: Press and hold, drag slowly across the pad (about 2 seconds).

Tip: Windows "Enhance pointer precision" is the most common source of acceleration. Turn it off in Control Panel > Mouse > Pointer Options. Some gaming mice also have firmware acceleration on high polling rates — check the driver app.

How to use the Mouse Acceleration Test accurately
Mouse acceleration is a non-linear scale applied between the physical motion of your hand and the on-screen cursor. With acceleration off, moving your mouse 10 cm always produces the same pixel travel. With it on, a faster swipe produces more pixels than a slow swipe of the same physical distance.

Mouse Acceleration Test
Because you control the physical distance of both swipes, the ratio cancels out DPI, monitor resolution, and display scaling. It isolates the acceleration curve itself.

- How This Test Detects Acceleration The test compares the pixel-per-inch rate of two swipes of the same physical distance — one slow, one fast. The math is dead simple:
- The Usual Suspects Windows "Enhance pointer precision": the #1 source of acceleration on desktop. Off by default in gaming setup guides for a reason.
