On the Steam discussion for FAR, it seems like someone else had a similar issue:
Do you know of a reason I can't use my controller with the fix? I remove the fix and my controller works add it back and it stops working. I am sure the issue is something I am not seeing in the ini.
The creator of the fix suggested the following:
Probably because the Steam client DLL is loaded early, which causes the new Steam Overlay features that have to do with gamepad input to hook in a different order than usual.
Run the game in Big Picture Mode and then check to see if you can configure your gamepad using Steam's new input functions.
While the user said this didn't help them, they followed up and said this solved their problem:
If anyone uses a Nvidia Shield Controller like I do for PC Gaming then you have to have this line set to false unfortunately. I am guessing Nvidia Bloatware is what is providing my system with the controller functionality. Make sense. Hope this helps.
DisableBloatWare_NVIDIA=true change to DisableBloatWare_NVIDIA=false
