vrpicasso Minimum resolution, refresh rate, bitrate, scaling / alignment, being true VR etc. Because right now I see comments on Reddit where people say "why is VR porn so shit" and it's because of the terrible, poorly shot and edited scenes which plague every aggregate site and which apparently NO ONE including those putting the scenes out has even watched with a VR headset.
I think many of the points you raise here is the reason many niches and kinks fails or garner little attention. There are studios on this site that shoot content I love in 2D but I can't watch these scene from these studios in VR because the quality is horrible- low resolution, terrible scale, wrong angles, stomach camera, out of alignment and I could go on.
The content could be great if they just made some changes but the studios or person shooting them are often out of 'reach' - meaning they don't respond to constructive criticism and continue shooting the same low quality content over and over.
I've stated it before but at times I find myself speculating if some of these studios on SLR are just a single man's production that is more about fueling that man's fantasy of fucking mediocre pornstars and VR is just a way to fund this interest. As such he has no interest in changing as it spoils his fun.
