My 2 cents – arrived here at 4 posts; based on this, installed vorpx and tried to set up my beloved warcraft.
My understanding is, that only default vorpx mode (whatever that is..) ‘works’. The two zbuffer modes just display flashing horizontal lines..
Geometry mode, renders a tiny squished 3d rectangle (ie doesnt work).
So what you get from default mode, is ‘faraway globe mode’ (think star night sky). Head tracking with mousebutton works, though.
Thus: zero depth experience afaik?
I have previous experience using wow’s builtin stereo3d (not vr headtrack), which i can highly recommend.
On a related note, the trion-rift mmo used to support oculus, but alas they apparently dropped that support somewhere within the last 6 months :-/
