Just bought Far Cry 4 on Steam and I am having trouble playing with gamepad. The buttonmapping is totally wrong and sometimes no button works.

I have tried updating the drivers, tried reinstallning the controller, tried several other games to ensure that the control works (it does on every other game), reinstalling the game, playing in online and offline, googling for a solution, but to no good.

It cant be impossible to use a gamepad, right?

Would appreciate some help on this basic issue.
