Hopefully this video is useful for you VR guys still trying to get good image and smooth gameplay in RaceRoom. Enjoy.
I can't play RR in VR since a while now, even after reinstalling my system and RR from scratch. Where is the guide to even start VR once? S3S destroyed VR-support for me and i'm just enjoying sims that run in VR without hours of try & error.
On my side R3E starts pretty easy in VR. Not much I have to do other than selecting the Option telling something like "starting 64bit in VR" Do you have any launch-option set? Is SteamVR started and Running? If you have the Oculus Rift - is the Oculus-App running? (If you have that I guess so, as you are playing something else in VR)
