Mouse Acceleration Test
Capture two swipes of the same physical distance: one slow, one fast. Fast/slow pixel ratio near 1.00 means no acceleration.
Step 1: press and drag slowly for about 2 seconds.
Slow swipe
px: - / dur: -
Fast swipe
px: - / dur: -
Fast / Slow ratio
-
Drag slowly first, then drag fast.
How to use
- Follow the on-screen zones for slow vs fast drags.
- Drag slowly across a fixed physical distance on your pad (same start/end each time).
- Drag fast across the same physical distance — keep the path as identical as possible.
- Read the fast / slow ratio shown in the results.
- Press Reset and repeat 3–5 times to reduce hand variance before you conclude.
FAQ
What ratio indicates no acceleration?
A ratio close to 1.00 (roughly within ±5%) usually indicates no significant acceleration.
What causes acceleration most often?
Common causes include OS pointer acceleration settings and some mouse firmware behaviors.
Introduction
Mouse Acceleration Test compares how many pixels the cursor travels for a slow versus fast swipe over the same real-world distance. If acceleration is on, fast moves can yield disproportionately more travel.
Purpose
- Toggle OS features such as Enhance Pointer Precision and see the ratio change.
- Contrast vendor “raw” / linear modes against accelerated profiles.
Key Features
- Fast vs slow swipe pairing over the same physical path length.
- Ratio near 1.0 suggests little pointer acceleration in this test.
- Repeat-friendly workflow with Reset.
Common Use Cases
- Verifying “Enhance pointer precision” / OS acceleration really toggled off.
- Comparing vendor “raw” mode vs default driver curves.
Best Practices
- Measure the same desk distance for both swipes; user error dominates bad ratios.
- Repeat several times — one sloppy slow drag invalidates the pair.
Comparison metrics
| Metric | Reading |
|---|---|
| Fast / slow ratio | Near 1.00 ± ~5% → little acceleration in this two-swipe test; far from 1 → investigate acceleration or inconsistent swipe length. |
| Repeat runs | Multiple trials reduce hand error — do not trust a single pair of swipes. |
