Each utility performs its work on this device. The keyboard, mouse and spacebar tools report events only while you interact with their clearly marked test area. The gamepad tester uses the standard browser Gamepad API, and the sensitivity calculator performs its maths locally. Tool input is not sent through GR8 GAMZ analytics.
Browser results provide practical observations, not a hardware diagnosis. A missed input can also be caused by focus, browser shortcuts, connection quality, operating-system settings or the way a particular game handles controls. Repeat a test and compare results before deciding that equipment is faulty.
When you finish, move directly between related tests or browse free online games to put the controls into practice.
