Apologies for starting slightly late - only Facebook seem to have utterly screwed my Rift (I.e. broken the drivers and also deleting my entire **** account with an update about an hour ago).
Needless to say I've been shouting at them rather than starting the server.
I'll join in a bit but may end up rage quitting if I can't hack pancake vision
As an update to anyone here affected - some googling has shown that you can still run the thing without the app up and running fully.
Fire up Steam, go to your library and then click the VR button (top right next to big picture mode (Who actually uses that??)).
It'll fire up steam VR and in the background the oculus app will slowly pop-up, fail to load, and then sit there (minimise it and ignore it).
You will of course have no access to anything Rift related but the functionality seems to be all there in Steam, so hopefully I'll be a little less ****ed when I join you in the server...
If you don't already you may need to run the OpenVR driver inside AC
