I'm hoping to avoid most of those issues with my Pimax 8K: 200 degrees of FOV, higher res, and the headset is relatively lightweight.The FOV within the headset is too narrow, tunnel vision, to simulate this in 2D, play 2D whilst wearing a S.C.U.B.A. dive mask.
The visual clarity and detail is nowhere near 2D's.
The headset gives me a "ice cream" headache after a few hours of wearing, (and no its not tight).
I can't play with the SRV in VR due to nausea from motion, revert to 2D for SRV work.
As for the SRV, I used to get nausea while driving in 2D and found that playing on a 3D screen (not VR) solved the problem for me. Everyone is different though.
It's possible that you may be able to acclimate yourself to VR after a while and avoid the nausea. From what I've heard, stop as soon as you feel the nausea, but retry after a long pause. I hope you can learn the enjoy VR.
