I couldn’t find a way to bind a double press in X4, so hold RB and tap X for example. These combinations are essential because there is no other way to use a controller to perform all of the necessary controls. It’s a shame because I would have invested a lot into the game if that was surmountable.
I tried binding in Steam but the controller settings in Steam are kind of terrible too. Half the time I don’t know what a setting does, and I feel like I need to do a training course to understand it. So I gave up and went back to Elite.
