MouseTester
Portable legacy utility for plotting raw mouse movement, polling intervals, velocity and sensor consistency.
About MouseTester
MouseTester records raw mouse input and turns the samples into plots that help inspect polling stability, movement, velocity, acceleration and possible sensor anomalies. Results are diagnostic signals, not a certification of mouse quality.
Version and origin
Version 1.5.3 is the final release of the dobragab fork of microe1 MouseTester. The project is open source under the MIT licence, but the release dates from 2016 and should be treated as legacy software.
