Forza 6 Apex recently got racing wheel support, and I wanted to try that as a preview of how it will work in Horizon. Long story short it didn't, but there has been a patch that may fix it so I will have to try again. I have a Logitech G25 and my #1 complaint about the Forza franchise has been the inability to use it.

Yes, kinda like TDU but not shit.
It exists (PC version, don't have an Xbox, very happy about this)
Logitech G25 works. Not super good at it yet but I'm sure I'll get better. Slides are hard to catch. I reduced the steering linearity in the center to make it easier to drive straight. Something about it feels slightly off compared to Gran Turismo and Dirt Rally which I can play a lot better.
Gameplay itself seems solid. I cranked the difficulty way up in terms of assists and the starting GT350 is hard to keep on the road.
Switching between 360 controller, keyboard, and wheel works well (all plugged in at the same time).
Graphics are solid.
Same stutters everyone is complaining about. Not game breaking but annoying.
Can't get much over 30 FPS on high with my GTX 1070. Will have to try medium.
Car customization menus laggy.
Had a few minor bugs such as the "explore your car" screen getting stuck bouncing around the tailgate.
I'm finding the cross country races just as infuriating as they were in FH2, I don't think the controller allows for quick enough steering corrections. I'm yet to try the wheel but with so much menu navigation I think that might get old fast (for example, I wouldn't be able to use the map properly).
