If your controller isn’t on before you start the game, it won’t work. Same deal if your batteries die mid-game the game will stop recognizing your controller after you change them.
Happens to me too.
Third party xbox controller, steam says it whould work pefectly with the game. If it isn’t on when I open the game it does not work.
What’s wierd is that the game actually changes the input icons to the ones for controller, but pressing any buttons does nothing. Like it recognizes a controller is connected, but can’t communicate with it.
Something similar to add. Forgive my ignorance I didn’t know if it has something to do with the game not truly supporting the controller and something to do with the steam support for controllers that games don’t directly support but just swapping back n forth from a dual shock (not aftermarket) and USB 360 controller I have to relaunch the game for the inputs to be recognized.
Haven’t checked after-patch, but before patch if your controller suddenly disconnects, game not auto-pausing. Happily I encountered this not in mid fight
