What is Mouse Acceleration?

Mouse Acceleration means the distance your cursor moves depends on **how fast** you move your mouse, not just how far. In competitive FPS gaming, this is generally considered bad because it makes building muscle memory nearly impossible.

Acceleration OFF (Raw Input)

1cm of mousepad movement = 100 pixels on screen. Faster or slower movement doesn't change this.

Acceleration ON

Slow 1cm move = 50 pixels. Fast 1cm move = 200 pixels. Predictability is lost.

About Mouse Acceleration Checker

### The Silent Killer of Muscle Memory Mouse acceleration is a "feature" where your cursor moves farther depending on how *fast* you move the mouse, not just how *far*. While this is useful for small office trackpads, it is disastrous for gaming. In a First-Person Shooter, you want 1:1 raw input—moving your mouse 5cm right should always turn your character 90 degrees, whether you move that 5cm in 0.1 seconds or 1 second.

Our Mouse Acceleration Checker helps you perform a physical diagnostic test to see if Windows "Enhance Pointer Precision" or a hidden driver setting is sabotaging your aim.

### How to Detect Acceleration (The Swipe Test) 1. **Setup**: Clear a wide space on your mousepad. Place your mouse against a physical object (like the edge of your keyboard) to mark the start point. 2. **Aim**: Place your in-game crosshair (or the tool's cursor) on a specific target. 3. **Slow Move**: Move the mouse slowly to the right until you hit the edge of your mousepad. Note where the cursor ends. 4. **Fast Return**: Quickly flick the mouse back to the left, hitting the keyboard edge (the start point). 5. **Evaluate**: * **No Accel**: The cursor returns exactly to the target. * **Positive Accel**: The cursor overshoots (moves too far) because you moved fast. * **Negative Accel**: The cursor undershoots (stops short) because the sensor malfunctioned (spun out).

### How to Disable Acceleration Permanently * **Windows Settings**: Go to Start > Mouse Settings > Additional Mouse Options > Pointer Options. Uncheck **"Enhance Pointer Precision"**. This is the #1 culprit. * **Mouse Software**: Check Razer Synapse, Logitech G Hub, or SteelSeries GG. Ensure "Acceleration" is set to 0. * **In-Game**: Always enable **"Raw Input"** in games like CS2, Valorant, and Overwatch. This forces the game to ignore Windows settings.

### Advanced: The "MarkC Mouse Fix" For older games (like CS 1.6 or Quake Live) that don't support Raw Input, you may need a registry edit known as the "MarkC Mouse Fix" to completely remove the Windows acceleration curve. Modern games generally don't need this, but it's a good safety measure for retro gamers.
