Having also received my G2 today and ditched the family for the evening to play with my new toy instead, I thought I would pop on here to give my findings, but what you have stated is exactly my experience so far also. Maybe I just need a few days to get used to it, but I find the Rift S more comfortable and easy to adjust, and although the text is blurrier with the Rift it is generally more readable across the whole area I can see, unlike the G2 which is sharper directly in the middle where I am looking, but out of focus everywhere else.
Not going to give up yet, but so far I am feeling pretty underwhelmed (having waited 4 months) and am struggling to see why I just spent £650 for a (so far) marginal upgrade over my Rift S.
Time will tell....
what GPU?
If you are seeing a marginal upgrade over a RiftS something isn’t right
