About Vector Precision Labs
Engineering calibration tools for serious players.
We build browser-native, zero-driver hardware measurement protocols to give gamers, designers, and competitive esports athletes absolute confidence in their input devices.
Our Mission
For decades, peripheral manufacturers have printed CPI / DPI specifications on boxes without accounting for real-world variance. Lens mounting tolerances, skate thickness, and pad friction introduce up to 5% deviation in raw tracking output.
Check Mouse DPI was founded to provide an open, transparent, and mathematically rigorous testing suite that anyone with a simple desk ruler can use in under 30 seconds.
Zero-Telemetry Privacy First
Unlike desktop vendor software that requires resident background bloatware and continuous network telemetry, Vector executes 100% of motion vector mathematics locally in your browser's JavaScript sandbox. No coordinates, cursor positions, or hardware identifiers ever leave your machine.
Sensor Telemetry Research
Our laboratory bench conducts ongoing research into USB micro-frame packet timing, 8000Hz polling rate CPU scheduling, and surface optical flow algorithms across PixArt, Logitech, and Razer optical sensors.
