Tests/Pixel Accuracy

Mouse Sensor Test

Analyze raw optical sensor motion, detect pixel skipping artifacts, and measure tracking consistency across smooth and rapid stroke patterns.

💡 Tip: Draw smooth circles or continuous diagonal lines on the pad to test for sensor jitter, angle snapping, and pixel skipping.

Common Sensor Performance Artifacts

High DPI Jitter Noise

Ripple Noise

Setting your sensor to extreme DPI values (e.g., >6400 DPI) amplifies microscopic surface flaws and hand tremors, causing jagged cursor ripples.

Pixel Skipping

Windows Scaling

Disproportionately high Windows cursor multiplier settings force the OS to skip screen pixels during movement. Always keep Windows pointer speed at 6/11 notch.

Hardware Angle Snapping

Linear Prediction

Firmware prediction that forces near-horizontal movements into perfectly straight horizontal lines. Great for drawing lines, bad for organic aim curves.

Sensor Smoothing Latency

Input Delay

High DPI settings (above 3200 DPI on older sensors) often activate internal frame smoothing algorithms, adding 2–6ms of input lag to tracking.

Mouse Sensor Test Frequently Asked Questions

  • Pixel skipping occurs when Windows pointer precision (acceleration) is enabled, surface dust obstructs the optical sensor lens, or high DPI settings amplify micro-hand tremors.
  • Angle snapping is hardware-level smoothing that forces diagonal pointer motion into straight horizontal or vertical lines. Esports players turn this off for raw 1:1 mouse input.
