I think what would be interesting to know is the location where you flew whilst trying VR (as some have stated above). If you fly over the Grand Canyon or another remote location versus over NYC, your experience will be vastly different in terms of FPS and graphics settings. You can’t compare the two from a GPU/CPU load perspective and your VR experience will be vastly different between the two locations.
I plan on doing mostly bush flying in the sim in VR as my rig is not good enough to do VR properly in big cities. But in the wilderness it should be a fairly good experience (still to test) based on my current FPS on a 4K TV.
