Like I said, as long as you're not flying around- moving within it, then your inner ear doesn't care. Turning your head doesn't count. I don't see a need in a code-in-VR system to move like that. And most VR games solve this my having your teleport instead of translate.

I think the barf routine is because when your brain senses your vestibular system not working it thinks "oops I must be poisoned" and tries to make you throw up.
