Seen is not the same as played. Call around to a friend that is setup for it and give it a go. I'm not the only one saying that static screen shots / Youtube videos don't do it justice. This is graphical treat even without RT, but with it just pops.
I have seen in that my housemate is sat downstairs with it on the same monitor as me. We also tested 4 cards, GTX1070, 5700xt, 6900xt & 3070fe. It really didn't wow me or anything tbh. It looked very much like anything else from the last few years graphically. In fact the NPC's seem worse than RDR2 and the facial animations etc on most pretty poor. The city had nice areas, some nice details but it didn't stand above anything particularly previously released.
