Interesting.
It does appear to be rather laggy in their version though it seems.
I might just have to go with using a Kinect and background removal and dropping that as a sprite in the game or something at this rate.
Also of interesting note I can see that the Oculus Touch controllers seem to lose tracking a few times in that demo which is not promising. The layout of the controller does seem to better suit that sort of game but hopefully the tracking is as good as the vive.
