Sorry if that question been answered before, but is the VorpX is a seated only experience on the Vive? I played a VR mod of Doom 3 and Penumbra and they were fully roomscaled, I had to go on my knees to crawl inside corridors etc. Thx! :)
In general seated or standing in place, but there also are a few games that allow basic walking around. The requirement for that is that the new Direct VR feature works with the game and that the Direct VR handles positional tracking. Currently this means: Fallout 4, Bioshock 1+2, Bishock Infinite, Aliens Colonial Marines.
