Got full wheel support working (clutch, H-shifter, FFB) and it feels great from the cockpit view. Still waiting on Fanatec to see if I can get their SDK - I really want FullForce in there as well. If I get that, I'll do a full "simulation" physics model (currently I have "Arcade" and "Simcade").
I'm really pleased with how well this works, so my next big feature is going to be - VR! Really excited about that one, being able to play my own racing game in full VR on my sim rig is kind of an amazing prospect, not gonna lie.
