I bought Dirt Rally a while back. I installed it and made sure it was working in my Rift. Since having a quick go to make sure it was working in the Rift I have reinstalled windows 10.
Tonight I tried to play it and couldn't. My positioning was all wrong. Instead of sitting in the drivers seat I was sttting on the back wheel. Does anybody have any idea why this is happening? I have the Oculus home version Dirt Rally. I have no issues positioning wise playing Assetto Corsa or Project Cars 2.
You can try recentering by pressing the Oculus button on Touch and select reset view. The game itself may also have its own recenter function, please check the settings. If that doesn't help, do a full sensor setup in the Oculus app settings.
