If it's the latter, there is a small chance that you would not have the same motion sickness problems with a VR HMD as you do with FPS gaming. Most of the headsets on the market today use 6-degree-of-freedom tracking for the head and hands. So if you move your head, the view does update accordingly. Actually, I'm not even aware of any headsets that are still available for purchase that have 3-DOF head tracking, though there are a few like the Vive Flow that have only 3-DOF controllers.

Headsets like the Quest 2 and Valve Index also have extremely high screen refresh rates (120hz and 144hz, respectively) that have practically eliminated for most people most of the motion sickness problems that can be attributed to the hardware alone. Granted, there are still some dodgy apps out there. I would avoid anything based on 360 video content in your case. Hell, I don't really have any motion sickness problems and I avoid 360 video content, just because I find non-interactive stuff to be a poor experience overall.

I wouldn't go out and buy one right away, but if you run into someone with a Quest 2, I'd encourage you to try it out. Supposedly, Meta is about to release their next iteration of headsets, whatever "Cambria" or "Quest 2 Pro" or "Quest 3" are supposed to be, which should be even more powerful.

The point I was trying to make in my post was that GP didn't know what he was talking about and that devices like the Lenovo T1 would be a lot worse for the kinds of issues he was mentioning than the VR headsets he was complaining about.

Thank you for the insights, It makes perfect sense for why VR headsets with greater refresh rates and 6-DOF might not make me sick. I'm going to try it when I get a chance.
