By the way: all Bethesda-games are quite good to be played with Oculus Rift. They deliver a very nice vr-experience. Not to fast gameplay and very focused on exploring. I hope Ralf will all of them get to work properly without graphic issues and with positional tracking.
What woks really good and out of the box besides Skyrim is Fallout 3. I had a problem, which caused crashing, but it seems one of the mods/patches I posted in this forum yesterday helped.
Skyrim is at the moment vorpX best supported game overall. Oblivion looks very good in 3d, but vorpX support should be improved to enhance conveniant gameplay, especially this fov-issue is at least anoying.
