Smoothness & tracking-precision test

The smoothness test evaluates sensor tracking precision and cursor fluidity. Drawing a trail on the canvas makes dropped frames, jitter or drift easy to see — critical for FPS players and digital designers.

How to test

Hold the left button and draw circles, straight lines or other shapes at a steady speed. A continuous, clean trail means good tracking; obvious jagged steps, breaks or jumps may signal a sensor problem or low polling rate.

What affects smoothness

Sensor type: flagship optical sensors offer higher tracking precision. Polling rate: more samples per second means a smoother trail. Mousepad surface: different materials track differently — cloth pads are usually the most stable. LOD: an overly high lift-off distance can add stray cursor movement.

How to improve it

Keep the polling rate at 1000 Hz or higher. Use a quality mousepad and keep it clean. Clean the sensor window under the mouse regularly. Calibrate LOD and angle-snapping in the mouse driver.

Who is it for

FPS players need precise aiming and stable tracking; designers rely on exact cursor control; and second-hand buyers can quickly spot dropped frames. The smoothness test is the direct way to judge a mouse sensor.

FAQ

What does a smooth trail look like?

Hold the left button and draw a steady circle or straight line. If the line is continuous and clean with no breaks or jagged steps, tracking is good; visible jumps or gaps point to a sensor issue or a low polling rate.

Why do my straight lines come out jagged?

Usually a low polling rate or limited sensor precision. Try raising the polling rate to 1000 Hz first, then clean the sensor window and the mousepad surface.

What does the average spacing mean?

It is the mean distance between neighbouring sample points, in px. A smaller spacing means denser, smoother sampling; a large spacing often means dropped frames or a low polling rate.
