I've been testing out the VR demos found here:
http://www.worldviz.com/products/vizard/oculus and I'm finding that, out of the box, these demos are quite disorienting. It seems like the projection is askew, and I can only use the headset for about 30 seconds before becoming nauseous. This isn't an issue with my Unity builds, and Half-Life 2 has been running fine in VR mode. Any thoughts?
