Thanks for the pointer, will see if this becomes my first purchase at A Festa! In general a bit more expensive than R18, but since you actually own the movie, will be worthwhile it seems. I am guess the quality is much better although it likely won't show up on my pithy Oculus Go....you are pushing me closer and closer to upgrade to the Oculus Quest 2!
I recommend Afesta too for those titles available on that site.
Oculus Go was my first headset and beside some drawbacks its still a good device for JAV.
Biggest issue for me was overheating. Playing 4k video put some heavy load on the Oculus Go and as there is no active fan, i usually get heat warnings and eventually the headset would stop working after 20-30minutes. Also you are limited to 4k content, so all the western 6k/7k/8k content wont play on the Oculus Go, but its not relevant for JAV. Unfortunately western VR is still bad for various reasons that i almost exclusively watch JAV.
Quest 2 is definitely a nice upgrade:
-SDE is much less noticable
-overheating issue is gone thanks to much more powerful cpu+active fan
-can play 8k videos (czechVR has the best videos regarding image quality)
-you can use players that use oculus timewarp layers technology for videos: the rendering technique used by Pigasus player (skybox is gonna get that upgrade too) gives much better image quality, that is most noticable on lower res videos (4k). I dont know if its noticable on the Oculus Go as well (try playing a video on Oculus Gallery which uses timewarp layer vs. in Skybox or other player of your choice). Drawback is that you cannot zoom, but if your IPD is close to the median you wont have issues.
-you can use it for PCVR as well, means using all players available on PCVR (whilgig, heresphere..) and the very popular player Heresphere will get a Quest 2 port with beta test probably starting this weekend according to the developer.
-there are countless games in the Oculus store, so its also a very fun gaming&fitness device. Keep in mind thats its very different than games on the Go as the quest2 is a 6dof device
Keep in mind that the VR headset right now is not the limiting factor for image quality, especially in JAV, its rather the resolution of the videos itself, so upgrading your headset wont give you significant image quality boost. I am still hoping for japanese studios upgrading their cameras to 8k this year, as many western studios will probably do.
I noticed some people on reddit were upscaling their VR videos using Topaz video enhance AI. Its an AI based tool to upscale videos with pretty amazing results. I did some testing to on a 10sec scene from a JAV VR video. The side by side comparison is pretty amazing (though still far away from native 8k). Unfortunately encoding time is crazy, upscaling this 10second scene to 8k took me almost 2 hours.
Quest 2 is much more limited than PC VR, but al least the screen has more resolution than Oculus Go, and you can apply some supersampling.
Quest 2 is actually the most used device on SteamVR (share of 46%). You can use it very well as an PCVR headset (USB-C or Wireless airlink/Virtual Desktop). I didnt noticed any quality difference comparing to my Odyssey plus that i had before.
