What? Give me a break, the ONLY difference is VR includes head tracking and has a headset that blocks out external view for more immersion.
Clearly you have no idea what you are talking about. VR and 3D glasses are very different other than one commonality - they both display 3D. It ends there. I have used 3D displays and shutter glasses, even earlier 3D (non-vr) HMDs and various iterations of all 3 for the past 10 or more years and I can tell you that they are not nearly the same and that trackIR (also a owner) will not close some imaginary small gap between 3D vision and VR that you (incorrectly) perceive. They are not the same nor are they nearly same. Tell me, is the scale 1:1 with 3D vision? Can you physically walk around your ships cockpit? Can rotate a full 360 degrees while maintaining head and positional tracking and still see the game? Does it give you a high in game FOV? The answer to all of them is no - and they're just the tip of the iceberg when it comes to the differences. If they were the same I'd have clean pair of 3D vision glasses right here instead of these dust covered reminders of the past.
TBH, the shutter glasses give quite a good 3D experience and if linked to TrackIR, they would be just as good as the other VR headsets with the exception that you don't have an enclosed area with your own monitor inside it.
Then grab yourself a shoe box or put a sheet over your display get under it and go to town - you just did what even Valve and Oculus could not, invent a really cheap VR experience....
(Optics, they're for pansies, completely needless - right..?)
Enclosed area with a monitor inside?! Seriously go get a demo of a Rift or Vive...You have not a clue.
You don't need mods, it works fine as it is. Even the orbit paths have a 3D look and the stations, inside the ship and other stuff is pretty good. Not as good as some games I've played with them (WoT for example) but good all the same.
Helix mod site hosts a fix for 3D vision in Elite, after following that scene for a number of years I can tell you that the folks there do not create shader packs for the hell of it, they create them because they are required and NVidia refuse to the fix such issues themselves, they essentially abandoned the tech in every sense other than still selling the kit, it was bad 5 or more years ago, its practically dead now. Which verges on being criminal in my eyes.
Anyway, no - 3D Vision does not work well in Elite without the Helix Mod fix unless yesterdays patch changed something.
