Hey! Sorry to hear you had problems. The FOV is reasonably high - 85 deg vertical. I think it's the lens distortion effect that's giving you the most trouble. The default Unity shader for that is rather bad and I've always had trouble adjusting it to not screw with screen edges, but I didn't expect it to cause motion sickness. That's the unfortunate part of doing VR dev daily - you have no idea what causes motion sickness anymore, because you're so immune to it.
The video is private, so I wasn't able to have a look.
Thank you for giving it a try :).
