Doom VFR / Oculus issue may be a bug caused by SteamVR.

Update 2: An update to the SteamVR Beta notes “added placeholder hidden area mesh for Rift users as a work around for Doom VFR and other titles experiencing launch issues.” We’re frankly not sure what that means, but it suggests the failure of Doom VFR to launch on Rift is a temporary bug and not related to the ZeniMax lawsuit.

Edit - People reporting that the SteamVR update worked, it is now running on the Rift.
