With Unity 5 Profile (copy for warframe 64 exe) it has good g3d!!!
The shaders and reflections need some work, but the g3d vr looks well and awesome. Only have the fov problem playing in full vr (not in immersive mode). I tweak the fov with vorpx until max, it looks ok (should be about 110), but i have to play with unsharp warframe than.
Maybe some of our vorpx experts can have a look and tweak a profile??? :) :)
