If you mean orbit lines outside of FSS, then I have seen them with an NVIDIA GTX 1080 Ti/VIVE Pro combo. At release of 3.3 and before one of the most recent updates the blobs were not visible on the VIVE. As for gravity wells, I am guessing you mean the concentric circles on the HUD on approach to bodies while in super cruise - if so those have been visible in the VR (VIVE) since I started using VR with Elite.
No, I was referring to orbit lines in the FSS (not the orbital plane, which is shown), and I was using the terms blue blobs and gravity wells as the same thing (in the FSS). I rarely use orbit lines when I'm playing.
This is a thread referring to the issue with orbit lines in the FSS.
