+1 for the idea! After flying around Mt. Rainier in VR, I wanted to show the wife as a passenger what it’s like so dual VR headset support popped into my mind.
I wonder if it would require dual GPU’s(/CPU’s?!) if the passenger simply got fed the pilot’s view like a movie. Obviously, it would be more fun if the passenger could look around independently but then a lot more computation would be involved. I imagine a passenger just being fed the pilot’s view would find that a lot more nausea-inducing as all the view changes wouldn’t be connected with their own head movement.
