Thankyou for the feedback! it seems the visual - vestibular contrast is the biggest flaw when playing.
There has been many people who say that they had similar sickness to the previous posts, but over time have gaines their "cyberlegs", taken from "Sealegs" from sea sickness, but applied to cybersickness.
Has anyone had the experience of cybersickness but has gradually got used to the Rift? If so, what do you thing changed when you played the game?
Again thankyou for the replies, any part of your experience is good as it help me to choose the most important area to solve and what users feel is the key issue.
