My own stick is correctly identified in steam as a FFB Sidewinder 2. However you should know although I use the steam install I do not use steam to launch the game.@Peppermint Barnstorm
Thx for your answer.
I can only set Buttons in Game, which I have define in Steam. For example I can set the X Axis, because the Gamepad in Steam has a X Axis. But I can't set the Z Axis for example for throttle, because the Steam Gamepad has no Z Axis.
Can you look in Steam is Joystick correct identifed?
I run 2 older accounts that don't require a steam login so I use Wine 6.0 Stable instead of Proton. I don't know how old your account is but if you can run the launcher with wine instead of steam then perhaps that might help?
