Seems to work here. I just launched wow from the battle.net client with VorpX running in the background and it started up fine. Im not a wow player so im not sure how playable it is, but i did get in-game and walked around a bit. Unfortunately you have to hold the mouse button down for head-tracking. Not sure if there is an option in the in-game vorpx config to fix that, and i dont care enough to look any further for a game i dont play :)
