Newsbrief: Following the news that Valve added a special section on Steam for VR-supported games over the holiday period, the company has now launched 'SteamVR', an experimental VR mode for the Steam client. As spotted by Road to VR, by starting Steam with "-vr" on the command line, you can boot Steam Big Picture mode directly into this new VR mode, compatible with the Oculus Rift dev kit. You'll need to opt into the Beta Update in the Steam tools options if you want to try it out. Comments on the forum post from Valve developer Joe Ludwig suggest that there are teething problems right now, as development continues.
