About Mouse Drift

🎯 What is Mouse Drift?

Mouse drift occurs when your cursor moves on screen even though the mouse is completely stationary. This is typically caused by:

  • Dirty or dusty optical sensor
  • Reflective or transparent mouse pad surface
  • Sensor malfunction or degradation
  • Electromagnetic interference
  • Low-quality sensor in budget mice

🔧 How to Fix Drift Issues

  1. Clean the sensor: Use compressed air or a cotton swab with isopropyl alcohol
  2. Change your surface: Use a proper gaming mousepad (not glossy or transparent)
  3. Update drivers: Install the latest mouse drivers and firmware
  4. Adjust lift-off distance: Lower LOD in mouse software if available
  5. Check USB connection: Try different USB ports or use a powered USB hub
  6. Replace mouse feet: Worn feet can cause uneven sensor height

📊 Drift Severity Levels

  • Excellent (0-2px): No noticeable drift, perfect sensor performance
  • Good (2-5px): Minimal drift, acceptable for gaming and work
  • Fair (5-10px): Noticeable drift, may affect precision tasks
  • Poor (10-20px): Significant drift, troubleshooting recommended
  • Critical (20+px): Severe drift, immediate action required

💡 Testing Tips

  • Place mouse on a stable surface
  • Don't touch the mouse or surface during testing
  • Test for at least 10-15 seconds for accurate results
  • Avoid vibrations (music speakers, fans, etc.)
  • Test multiple times in different conditions

Note: Some minimal drift (1-2 pixels) can be normal due to micro-vibrations in the environment or sensor sensitivity. Only consistent or large amounts of drift indicate a problem.
