Broke mine as well I was supposed to wait for VR support to release next month :). Forza Horizon 4 plays really well if you have an Xbox one controller. It's the first game I've played that uses the impulse triggers on PC. I'm only going off the demo(which is fantastic) but that would be my pick for casual racing. I've not tried PC2 and AC with a controller but I much prefer AC with a wheel. For what it's worth Competizione is apparently quite playable with a controller:
Forza 7 tbh. I have all three and project cars 2 would be my second choice for controller. On a wheel I would go for project cars 2 but I do like them all on the wheel. PC2 can be played on controller but I found I had to play about with a lot of settings to get it drivable.
I would definitly take project cars 2 for a casual with controller, Assetto Corsa 1 is more a sim.
PC 2 or AC for a casual with a xbox controller peeps?
So much for my resolve to wait a month. Cheers!
