Mouse Drift Test
Place your hand off the mouse, press Start, and wait 30 seconds. The tool samples every pointer event and reports total drift, max delta, and movement count.
Keep your hand OFF the mouse during the test. Move the cursor into the pad once, press Start, then let go. We sample every pointer event until the timer ends.
Hover your cursor inside this pad and press Start. Do not touch the mouse until the timer finishes.

Tip: laser sensors drift more on glossy surfaces. Optical sensors drift on transparent or very dark mats. A good gaming mousepad eliminates most false positives.

How to use the Mouse Drift Test accurately
Mouse drift is unwanted cursor movement when your hand is not touching the mouse. It happens when the sensor imagines motion — reading micro-variations in the tracking surface as real movement and reporting them to the OS. A healthy gaming sensor should report exactly zero counts when the mouse is stationary.

Zero pixels total = a perfectly still sensor. A couple of pixels over 60 seconds is normal electronic noise.

- Laser vs Optical Sensors Laser sensors (Philips Twin-Eye, older Razer) see fine surface detail, which is great on cloth but triggers false movement on glossy, painted, or highly reflective desks.
