When I last tried the hidden Oculus option (a year plus ago), it worked, but left me with the feeling like I was in the front row at a movie theater (it was near impossible to see the HUD display(s)).
The vorpX G3D option, in my experience only, works better than the hidden Oculus option, but for my default game/vorpX settings, I think my graphics card (GTX 1070Ti) isn’t up to the task, as the 3D is great, but the graphics have enough pixilation going on, that looking at certain buildings felt like an early 32-bit version (e.g., Playstation or Sega Saturn).
