An intresting post came up in the OculusNSFW subreddit today, asking ‘how much better is Oculus/Vive/PlaystationVR porn compared to smartphone vr porn?’

In general, the consensus seems to be that there isn’t much difference, aside from resolution, but even there a Gear VR with the lastest Galaxy smartphone will come close to the best VR headsets. The main difference between smartphone/mobile VR and high-end headsets such as the HTC Vive is that mobile doesn’t provide 6DofF. However, this isn’t an issue in recorded VR porn videos, although gaming is a different matter. Unfortunately there is still a very limited supply of digital VR porn videos and games.
