The “Gamepad” tab in Settings is deactivated/unclickable by default. To activate it, you will need to follow the steps below:
- Go to Settings > Game Tab > Camera
- At the bottom, click the check box for “Gamepad Mode”
Once done, you should now be able to select the “Gamepad” tab.
Note: If you do not have a gamepad connected to your PC, you will get an error message that says “Your controller has been disconnected”.
