The general consensus in that thread is that, while the Vision Pro can play “flat” porn videos on sites like PornHub, there is currently not an easy way to play 180 degree side-by-side videos on the Vision Pro, which is how most commercial VR porn is filmed.
The 360 video is junk. The games are where the fun could be, but the VR titles are all half baked and not well set up around 1 hand being occupied.
Of course those are not 3D. The VR 180 ones are the good ones, those you have depth.
