With the Oculus Rift CV1 now out in the wild (and my unit in my hands) as well as the HTC Vive (where is my Vive, HTC?!) gamers are now discovering some very cool things with VR gaming.
One of those is LibreVR, which is in an alpha state, and is "a proof-of-concept compatibility layer between the Oculus SDK and OpenVR". This means that any game that is exclusive to the Oculus Rift and is made by the Unity engine or Unreal Engine 4, can work on the Vive. In the words of Neo: "whoa".
Right now, LibreVR works with Rift exclusive Lucky's Tale (which comes in the box of the Oculus Rift) and Oculus Dreamdeck. The performance isn't perfect yet, but it'll improve as time goes on. We don't have our Vive headset yet, but when we do we'll be testing the hell out of this.
