Following Steps
- General steam “settings”.
- Controller “generel controller settings”.
- It automatically switches to “big picture mode” controller settings.
- Then select only “gamepad – configurationassistant”.
- Press button “back” and and close the settings.
- Start the game “XCOM 2”.
- Go to the “options”, “interface”, “Input devices” change to “controller”, save and close.
