What I did notice with the Crystal FOV which I hadn't noticed before with other headsets is that the trees follow you in sim racing games. They're generally 2D images and as they get to 10 o'clock and 2 o'clock in your vision I could see them rotate towards me out of the corner of my eye as they passed. Something daft but something I couldn't unsee.

I don't know how these people with triple monitor setups deal with that, it'd drive me insane.
