Esports Optical Sensor Precision & CPI Variance Suite

Mouse DPI Accuracy & CPI Deviation Analyzer

Is your mouse actually running at 800 or 1600 DPI? Measure physical sensor deviation caused by lens height tolerances and mousepad weaves, and calculate the exact in-game sensitivity correction factor.

HOLD LEFT CLICK & SLIDE EXACTLY 10 CM

Place a physical ruler on your mousepad. Press and hold left click at 0cm, slide horizontally to the target mark, then release.

Raw Counts: 0
Target Distance: 10 cm (3.94 in)

Sensor CPI Deviation
--variance

Complete a test slide to calculate variance.

Tolerable esports variance: < ±3.0%
Sensitivity Correction Factor
× 1.000

Multiply your in-game sensitivity (Valorant, CS2, Apex) by this value to match your intended 800 DPI muscle memory!

Example: 0.35 sens × 1 = 0.350

Sensor CPI Deviation vs Mousepad Weave

Heavily textured or worn-out cloth mousepads scatter optical sensor LEDs, causing up to 6% CPI variance between horizontal and vertical swipes.
