Hi,
during any race session that lasts longer than 10 minutes(test drive, rivals, career, multiplayer) then screen will automatically dim if you are using a racing wheel(I assume it is because it doesn’t see any button inputs since you are just using the wheel+pedals+shifter) this obviously makes the game completely unplayable. This has been going on for the past 2-3 months but I have been too busy with school too care about forza 
and I figured it was a big enough problem to have been fixed by now but apparently not! I have seen posts about this on other forums but I didn’t see any on the official forum so that’s why I’m writing.
I just wanted to bump this issue. The screen still auto dims every 10 minutes when using a wheel. This really deters me from ever bothering to play Forza 6 which is otherwise a solid game.
I just got the same issue in Assetto Corsa with the Logitech G920, so it’s an Xbox problem.
It happens in FH3 too
Not if you just press a button on the G920’s wheel
Edit: As the person above said, it’s an Xbox problem, it’s not a game problem. After looking into it, apparently it happens in Netflix, Amazon Prime, and some other games.
Yes, I could tap a button on my wheel every ten minutes but that is extremely distracting and breaks my immersion which means a lot during a race. They still haven’t fixed the issue.
Just press rear wiev button every now and then, like when racing…doesn’t that help?
