I was vaguely aware of vorpx, but I didn't mention it because I didn't want to give the wrong idea. I understand that program is mainly about trying to hack in "real" VR support (motion tracking etc) for normally flat games- that's explicitly not what I'm looking for.
It looks like that's it's main selling point but I do see some references to being able to use a virtual cinema mode instead. I can't find much about that feature because it's not promoted very prominently, and their website is terrible in general.

Have you used it yourself in that mode? Does it successfully give the effect of playing games on a 3D projector, like the 3D movie-playing apps can do?
