I made the maiden flight with the Reverb today, coming from an Acer AH101. Both are WMR, thus the transition was completely smooth (albeit I agree, WMR as such being clumsy).
I really like the higher resolution. Notably, I can discern things like Papis and runways from a greater distance than previously. Despite, while all gauges, GPS etc. are are perfectly readable now, clarity of the scenery at a distance still isn't comparable to my 3440x1440 screen...
I was happy to not observe any performance degradation with my EVGA 1080Ti (which I was afraid of), neither under AeroflyFS2 nor Prepar3d4 (with the latter showing the same stutters/dropouts under difficult situations as before). I read some people felt kind of a tunnel seeing effect because of reduced sharpness at the borders, which I didn't experience, even though I kept an eye on it.
I also like the integrated headphones. The controllers work as such, but I didn't test them much as I don't use them usually anyway.
The only thing I dislike is cable management. The Reverb comes with a thick and pretty non-elastic double cable which is much more annoying than the previous Acer cable. I am still experimenting how to handle this one.
Overall, I expect to stay with the Reverb for some time. The next step for me might be some solution where I can combine the headset with viewing/manipulating my hardware knobs and buttons.
Kind regards, Michael
