I’ve been having issues with both FH3 and Forza 6: Apex where the game is not recognizing the correct gear. I’m using a Fanatec CSR with a ClubSport Shifter V 1.5 US shifter and the gearing is as follows
shifter----game
R--------- 6th
1st-------- R or 6th
2nd------- First
3rd-------- 2nd
4th-------- 3rd
5th------- 4th
6th-------- 5th
My computer recognizes all of the gears in their correct location and I have no issue with any games on Steam.
