Why You Must Turn Off Mouse Acceleration

If you play competitive shooters like Valorant, CS2, or Apex Legends, 1:1 raw input is mandatory. Windows natively applies an algorithm called "Enhance pointer precision." This is a mouse acceleration curve.

When acceleration is ON, moving your mouse 2 inches slowly might move your cursor 500 pixels. But moving your mouse 2 inches fast might move your cursor 1,200 pixels. This artificial scaling completely destroys your muscle memory, making consistent flick shots mathematically impossible. Our mouse acceleration test online engine detects this variance physically.

How to use the "Return-to-Origin" Test

You cannot test acceleration just by moving the mouse randomly. You must use a physical boundary.

  1. Place the left side of your physical mouse flush against a heavy object (like your keyboard).
  2. Click and hold the digital Puck on the screen above.
  3. Drag the puck slowly to the right side of the track.
  4. Now, quickly flick your physical mouse back to the left so it hits the keyboard again, and let go of the click.

If your digital cursor is perfectly centered where it started, you have true 1:1 raw input. If the Puck is far off-center (Origin Drift), an acceleration curve is modifying your cursor distance based on speed.

How to Fix Origin Drift

1. Disable "Enhance pointer precision" in Windows

Press the Windows Key, type "Mouse Settings" -> "Additional mouse options" -> "Pointer Options" tab -> Uncheck the box that says "Enhance pointer precision." Hit Apply.

2. Disable Acceleration in Proprietary Software

Open Logitech G Hub, Razer Synapse, or Corsair iCUE. Check your sensor settings and ensure "Acceleration" is set to 0. Some high-end mice have hardware acceleration built-in that must be disabled in the app.

3. What is Negative Mouse Acceleration?

If your puck ends up short of the center line after a fast flick, you are experiencing negative acceleration. This is a hardware fault. It means you flicked your hand faster than the optical sensor inside your mouse could track (exceeding its IPS - Inches Per Second limit), causing it to lose data and stop moving.
