Long-form guides connect browser observations to repeatable checks, safer settings and realistic hardware decisions.
Read observed pointer event rate, median intervals and spikes without mistaking browser delivery for a USB hardware certificate.
ControlsRead your own pad, set a deadzone from the number it reports rather than from a guide, and find the five faults that are decided by a measurement rather than a setting.
ControlsThe arrow-key driving set, the eleven action maps behind it, and the four recovery actions that get confused. Every binding carries the action id the game uses internally.
ControlsFour recovery actions that mean four different things, the pause filed under General, and the node grabber — where one mouse button does three jobs and only a colour says which.
ControlsThe publisher's twelve-step force feedback procedure in the order it must happen, the 112 tested devices with the two columns everyone loses, and the faults that are not settings.
SettingsThe deadzone and linearity controls with what each one actually changes, the fourteen numbered layouts nobody else prints, and why no recommended number appears on this page.
SettingsEvery keyboard binding, and the limit behind them: three steering states and two throttle states, which no setting in the game changes. What to do about it, and what to ignore.
SettingsSixty tested devices with the partial-support marks nobody reproduces, twenty-six advanced settings, and the device-order rule that explains a silent motor on a working wheel.
SettingsA stick sets a turn rate, not a distance, and no publisher documents it. Time your own 360° in each game and get the sensitivity that makes the second one feel like the first.
SettingsAim, sprint, crouch and focus all ship as hold or toggle. Starting costs the same either way; stopping does not. Measure the gap on your own hand, then choose.
ControllerA browser reads a gamepad once per drawn frame, so a controller polling rate test cannot see past your display. Measure the ceiling, then read your own number against it.
SensitivityeDPI only means something inside one game. The same hand movement is eDPI 800 in CS2 and about 251 in VALORANT, because the two games count in different units.
SensitivityConvert hip-fire sensitivity with a physical distance model, understand game-specific eDPI, and validate the result without assuming identical feel.
ControllerFix common controller detection problems by checking user activation, connection, browser support, competing apps and mappings in a controlled order.
ControllerA repeatable five-minute process for measuring analog stick center offset, separating drift from game settings and deciding what to try next.
KeyboardUnderstand missing and unexpected keys, test realistic gaming clusters, and avoid confusing browser shortcuts with keyboard matrix limits.
MouseMeasure suspicious click intervals, separate intentional double-clicks from repeatable extra events, and test connection and software causes safely.
I answer from this site only — the 28 browser tests, the controls library for 46 games, the sensitivity converters and the two games. I can tell you which page to open, how a tool works and what its result means.
I will not guess. If something is not on the site, I will say so.
