Gameplay > Graphics
If you disagree you're in the genre of games. Making an open world game isn't like making a linear game. In order to create entire worlds with all the nooks and crannies you can explore they have to sacrifice some visual performance. You can't have both... maybe not right now. But honestly the graphics do not ruin the game, far from it. Dark Souls had horrible framerate issues that would drop to a slow crawl for nearly entire areas. It wasn't pretty but damn was that one the greatest games of all time... that's my opinion at least.
Fallout, Knights of the Old Republic, hell Minecraft, WoW, Diablo, Counter-Strike, Amnesia Dark Decent, Silent Hill, Ultima, Final Fantasy 7 (don't even start defending that, the cutscenes were great but Cloud looked like Popeye) and so on. Games that didn't have good graphics at their time and don't really age well today but who cares.
Go play Tetris...
It's a joke, but for some games graphics play a high role in immersion, just like 3D vision (in fact less than 3D vision but these two aspects of realisation have high impacts, especially for those who are ready to buy high end material just for that)
Anyway : a sad truth > a beautiful lie
Some things said here are tough, I recognize it, but it's a matter of feeling, especially for those who put a great trust in what CDPR said, and said again a few times
For what I know the problem is never the developers themselves or their hard work, but some decisions coming from their Leaders and the communication that is made
The game is good, but lots of us are disappointed for good reasons, there is no discussion about that last point, which has not the same importance for everyone
And now it seems to happen for nearly every multisupport game, even PC based licences, which is sad and disturbing...
If only it didn't just for this game, which is to me (and to others I am sure) the most waited for the last years...
Another equation :
most hope = (risk of most disappointement) / (trust in devs)
And here trust in devs was really high, and the fall was tough too
