Re: I used to do this for a living
It likely varies per person. Lots of people experience nausea trying to play first-person video games on regular computer screens, probably for much the same reason.
(I myself experience vestibular migraines if I play for too long when I'm too tired. Fun stuff. One silver lining to the cloud of having to take Metoprolol is that it mitigates the effects. They're no longer debilitating, merely uncomfortable.)
And this isn't even full immersion stuff, just staring at a screen. The disconnect between body and vision is at least part of what causes car sickness and the like. I can see how full immersion would intensify the effect.
