Joe Ludwig, a programmer at Valve, has posted details of how developers can enable SteamVR in the recent Steam Client Beta. The mode is still experimental and requires an Oculus Rift headset, if you’ve got one to hand it’s a simple matter of starting the client with “-vr” on the command line.

Once Steam has started with the feature enabled, a new option for SteamVR will appear under Tools in your library, which needs to be installed. From there, you can grab update it to the latest beta by selecting SteamVR properties and opting into SteamVR beta builds. One more client restart with “-vr” and you’re good to go.

There’s already a community-authored guide too, if you get stuck:

Valve are expected to cover their plans for VR in detail this week at the Steam Dev Days in Seattle, more news on that when we have it.
