I haven't been able to get the Rift working in the combat tutorial demo at all. No matter what I do, the game never gives me an Oculus Rift option in the 3D graphics settings menu.
someone posted in the oculus forum that it works in the demo version. Weird that you don't even get the option... was your rift plugged in at the time?It is possible the OR support is not in the demo? Haven't tried that...
