Frequently Asked Questions (Cursor Smoothness & Sensor Trajectory Benchmark)
10-Item Technical FAQ & PointerEvent Telemetry Troubleshooting
What is cursor trajectory jitter?
Jitter refers to erratic, uncommanded cursor micro-vibrations caused by sensor optical noise, dust on lens, or bad mouse pad surfaces.
What is mouse angle snapping (prediction)?
Angle snapping is sensor firmware smoothing that forces diagonal hand movements into straight horizontal or vertical lines.
How does the trajectory smoothness canvas work?
Renders raw PointerEvent coordinate dots alongside smoothed Bezier curves to reveal sensor interpolation artifacts.
What causes mouse pixel skipping?
Pixel skipping occurs when low DPI combined with high in-game sensitivity causes the cursor to jump across multiple pixels.
How do I test my mouse pad surface for sensor tracking errors?
Move your mouse in smooth circles; uneven tracking or cursor stutters indicate mouse pad dirt or weave reflections.
What is Lift-Off Distance (LOD)?
LOD is the height above the mouse pad at which the optical sensor stops tracking movement (typically 1.0mm - 2.0mm).
Does high DPI increase cursor jitter?
Sensors operating near maximum native DPI (e.g. 26,000 DPI) can introduce minor optical sensor noise and jitter.
How do I disable mouse acceleration in Windows?
Uncheck 'Enhance pointer precision' in Windows Mouse Properties to ensure true 1:1 linear tracking.
What optical sensors are considered top-tier for esports?
Top sensors include PixArt PAW3395, Focus Pro 30K, and HERO 25K, featuring zero hardware smoothing or acceleration.
