Controller becoming unresponsive periodically

[Laraul]

Have you tried deleting the FFXIV.cfg file? It's under "User\Documents\My Games\FINAL FANTASY XIV - A Realm Reborn\" and contains your game pad configuration info.

There should be no need to "calibrate" an Xbox 360 controller with the game's "calibration" config, This should be true with any controller that uses Xinput. I would advise you to skip this unless your controller uses DirectInput.
