I've never had issues with VR even with 8hour sessions. I have an HTV Vive original pre-order. There were some very early games with bad locomotion systems that could cause motion sickness but I haven't seen any of those since the very very early days of VR. There are people who have spent 24hr+ in VR without issue. Not sure what you are basing your comments on. Modern VR standards are even better than what it was with my older PC setup (GTX 970 + vive). Way larger FoV and better PPI screens are making a big difference
