Before I recently bought my first decent wheel in four years - Thrustmater T150. Ie. playing with a DS4, since the T100 I bought a couple of years ago was terrible and has been gathering dust since week two or three.
1) DriveClub
2) Dirt Rally
3) Project Cars
With the T150.
1) Assetto Corsa (80% of my racing time since I bought the wheel)
2) Project Cars
3) Dirt Rally or DriveClub. I'm still terrible in Dirt Rally with a wheel, and I've played so much DriveClub the last year that I haven't felt compelled to play it much now with a wheel.
