The quest 2 is my first HMD, and I am not sure if the chromatic aberration I have is comparable with other people's headsets. My IPD is 66 and I use the third setting.
Description of the quantity of chromatic aberration on my headset: On the home screen, looking at the white text in the top left that says “Home” through the furthest left periphery of the lenses, there is a green ghost which extends inwards such that the ghost "e" overlaps around half way though the original "e".
Is this similar to other people's experience?
Pretty typical VR newbie observation imho. Try to avoid moving your eyeballs all over the place and just concentrate on your central views. Also, work on better head placement and try to avoid excessive light bleed from things like strong overhead lighting and sun lit windows.
Sooner or later you will work this all out and then just enjoy the immersion. I think that the Q2 panels are one of the best lcd's out there right now.
