A Valve employee known simply as “Programmer Joe” took to the SteamVR Steam Community to announce the addition of VR support in the latest Steam beta client.
How to try SteamVRAs of the most recent Steam Client Beta steam now supports an experimental VR mode. If you own an Oculus Rift dev kit you can try it out by starting Steam with “-vr” on the command line. Then press the Big Picture button to enter Big Picture + VR mode.
The first time you run you may need to do the following:
1) Run Steam in the desktop client without the -vr option
2) Find “SteamVR” under “Tools” in your library. (If you don’t have it installed, install it.)
3) Bring up properties on SteamVR and opt-in to the “Beta Update” beta. Let the update download.
4) Quit the Steam Client again and start it with -vr
Please use this forum to provide feedback on VR mode.
