It is the future of gaming, but currently has so many problems that prevent long game sessions for many people. Eyestrain, dry-eye, motion sickness, headaches, and these problems only get worse if your rig can't run a game at full frame rate. The interpolation helps, as does the fact that the head tracking is handled by a separate program that is always max frame rate even if the rendered game environment isn't, but VR just isn't close enough to reality to deliver the experience it promises.
I bought a VIVE back when it was $500. Still have it. Dusted it off to play Half-Life: Alyx. I got 5 hours in and I have no desire to finish it because the game physically hurts my brain to play.
I ask my Yas Forumsros who dropped a grand or so on the better and newer headsets; has this shit gotten any better?
