Got mine earlier today and binged. Ive owned the Q2, Q Pro, Reverb G2 and Pimax Crystal (pimax I returned).
Q3 is a very nice and noticeable bump up in image quality over Q2. I ran through DeoVR and also stored a couple of the giant file size SLR Originals (my favorite) directly on the device. Doing so told me our clarity issue is partially a content and not a raw resolution problem because the videos that the new 8k SLR camers produce have no equal, especially on close cowgirl riding etc.
But my point is, the pores on the girls face, the dripping cum (like in the Freya Von Doom video) etc. look better on Q3 than on any headset Ive seen aside from the Pimax Crystal (and honestly with the Crystal there is very little difference with the Q3 visually for porn).
While we are still not in earth shattering, holy grail levels yet (that will come with 4k per eye micro OLED displays paired with 10k + high bitrate videos), the Q3 experience of having a giant sweetspot, along with the bump in resolution produced a noticeable stepup on the higjest quality SLR videos and to a lesser extent things like WanksVR and CzechVR (which are also nice but dont contain as much granular detail as the 8k SLR setup). As should be expected it does almost nothing for lesser 5k and 6k content, aside from the aforementioned sweetspot enlargement.
If you can't tell, while Im satisfied with the Q3 and think its worth an upgrade for porn, what we really need is more studios with a setup like the one SLR is using. I'm not being a fanboy for the sake of it, just telling you what my eyes see.
Also, I'll take my opportunity here to plug continued (and more often) close filming. When SLR does closeup cowgirl, mish, etc. you can actually zoom the camera out a bit, thus exposing a higher pixel density and better image. Their cowgirl closeup where the girl almost touching the camera with her face and boobs allows you to get a huge portion of the 32 million pixels on screen for her BODY. This does look amazing, and it highlights the mediocrity of the far away shots even more. When you have a girl giving a blow job or doggy from 6 miles away the area of focus on her body is taking up very few pixels comparatively and you thus lose out on granular detail. So SLR, film close often would be my recommendation.
What does this have to do with Q3? Again, im trying to convey a way to play to its strengths and take full advantage of the device.
