Alright, I got my Reverb G2 last Friday, having submitted my pre-order in September.
CPU: Ryzen 5 3600X, GPU: Radeon RX Vega 64 with some tweaks (VGPU down, +50% PT).
My previous and first headset was the Samsung Odyssey+ with a pentile OLED matrix, so that's the only thing I will compare it to here, since that's all I know.
- Colors & blacks: Colors are clearly more washed-out, but still okay for me. Blacks aren't as good either, but they're pretty close! Better than I thought.
- FOV: Clearly better on the O+! The feeling of being "boxed in" is quite a bit stronger on the Reverb G2. Still okay for me though.
- Sweet spot: I think it's smaller than on the O+.. or maybe it just feels like it because of the resolution? I'd like it to be bigger than it is actually.
- Godrays: There, but they're very subdued. This I really love, because those were nasty on the O+.
- Comfort: It's a tight fit, and it's not as easy to "just remove for a few seconds", but other than that it's much better! No pain, no red marks left behind.
- Light bleeding: It's there for me unless I fit it very tightly. But in any case, it's quite a bit better than on the O+, so that's nice.
- Audio: Can't use the off-ear thingies, loud environment. They're super-easy to remove though, and my Beyerdynamic DT1770 Pro phones fit perfectly with the Reverb G2! Very good!
- Resolution: Jaw-dropping! The sharpness and detail levels really made me go "aaah!", "oooh!" and "wow!" for a while, it's a massive uplift coming from Samsung's pentile panels! Like a VGA to FullHD kind of uplift!! Amazing! This is what I bought it for, and in that department, it delivers!
- Distortion: Sadly, at least at my IPD setting (~61) I can see distortions near the centre when looking around. They're quite pronounced, too.
- Performance: I have reprojection off, and yup, it's bad and at times very stuttery on my RX Vega 64. This was to be expected. Actually, it's still better than I thought it'd be. Playable at least, with all settings at max. Framerate just isn't pretty. Where is my 6900 XT!?

- 60Hz mode not yet tested.
So, there are a few issues (sweet spot a bit too small, same for FOV, distortions near the centre of the FOV), but it's slighty better in a few areas and drastically better in terms of resolution, which really is an eye-opener! Maybe they can do something about the distortions with a firmware update? That's how Samsung successfully dealt with most of the barrel distortion on the O+ after all.
The O+ is indeed better in a few areas, as described above, but after having seen that much crisp detail, there's no going back for me, so I'm playing with the G2 now, despite the performance issues.
Now, as stated above, all I need is twice the GPU power! Like, pleaaase?
