Fanza and A Festa are two different stores.
Fanza has exclusive rights to almost all the important studios. It has DRM so it can only be viewed with their player, although there are ways to remove the DRM. The big problem is that the 8K versions have a very low bitrate. Used to be 11-15 Mpbs, now it's going up a bit with some titles at 18-20 Mbps.
A Festa has SOD, KMP, Prestige, Dandy, and little else. But the advantage is that it has no DRM, so you download MP4 files and use them with the player of your choice. It only has 8K versions of SOD VR, but with a bitrate of 100 Mbps, they look amazing. Too bad the SOD VR titles in the last few months have been crap....
I buy on Fanza the titles I really like, just to support, because their VR player is garbage. On A Festa the SOD VR titles I like, which this year has been one or two....
I can't understand what's wrong with this movie, I'm not able to see any difference with respect to other titles.... In fact it is most likely that most studios use the same 8K camera, provided by DMM / Fanza... For example KMP does not release 8K titles on A Festa, only 4K, which makes me suspect that it is because the 8K cameras they use are from Fanza...
It depends of your IPD, i.e., the distance between your pupils. In a mirror you can measure your IPD with a ruler, or better yet, go to an optician and have it measured, they usually do it for free. If you have a large IPD, you will notice more "binocular effect". With a large IPD the Quest 3 are better, because they have more FOV (field of view).
But you can improve the FOV and reduce the binocular effect in Quest 2, by changing the facial, the cushion that covers the headset, to get a little closer to the screen, and see more FOV. The facial that comes with the headset is designed to be used by people who wear glasses, without removing them, so it is far away from the screen.
It is not something to worry about, even if you have binocular effect you end up getting used to it. I have a HP Reverb G2 headset, which has a smaller FOV than Quest 2, and on top of that I have a large IPD, 69 mm. I have changed the facial for another one to see it closer, and I don't have binocular effect.
Is the quality from Afesta much better than those on filejoker and torrents?
