Pretty sure the things that show up as working with Vive will work, but the ones only supported by Oculus will not.
Install Revive and Oculus. I think it's required for Dirt Rally, plus there are some nice free experiences on Oculus. I can confirm that Oculus titles work with these headsets.
On a side note, I also picked up one of the $30 models (WVR3) just to see how they differed. Honestly, I'm a bit underwhelmed. There are some benefits, but the image clarity, brightness and color just doesn't seem to be there. It improved when wearing my glasses with it, which is something I don't normally need to do, but it just wasn't as crisp and colorful as the WVR2.
The IPD adjustment seems only useful for those who have an IPD which is less than what is considered common. Mine is pretty much dead-nuts on the norm, and it doesn't adjust wider than that. One thing which does seem much better is the refresh rate. It seems higher than the other units, making the experience less jarring. The 3D effect is also more pronounced. If the image didn't smear when looking around, it would be a pretty decent unit. Oh, and it has a much longer cord. Probably about 12'.
Physically, it feels more substantial than the other one, and it had a nicer strap, which comes pre-attached. The face pad is softer, but still not great, being fabric covered. The gamepad is the same as the WVR2.
If you are looking for a reasonably good VR HMD, for little money, the WVR3 is probably the one I would go for. But if you want it primarily for VR video, or games where you wouldn't do a lot of head movements (cockpit games, racing, etc) the WVR2 is probably the better unit.
