Start with the input that is failing
A controller that Steam cannot detect needs a different test from a recognized stick with a bad dead zone. Start with one connected device and record the current configuration before changing Steam Input.
Use the available cards for the relevant input or performance guide. Test in training before buying expensive gear or taking a vehicle into a full match. Mouse, keyboard, controller and flight bindings are not automatically equivalent.
A clean comparison beats several simultaneous changes
Restart when a setting needs it, change one variable, and keep a route back to the original setup. Do not install extra remapping layers just to conceal an unknown cause.
The controller guide separates older Build 0.11 reports from the published Season 2 changes. Neither is a test of every controller and action. Read each article's limits; an interface update does not establish current device compatibility or guaranteed FPS.
