So this is like the fourth or fifth major game where people have been outraged over graphics/performance or downgrades. (Off the top of my head, Watch Dogs, AC: Unity, Uncharted 4, now Fallout), maybe it's time to accept that this is the standard for next gen? You can only blame developers for so much when you should realize that the hardware for next gen systems is not as significant jump as was ps2 -> ps3 or xbox -> 360.
For pc gamers, consoles being the limiter has always been a hard fact. This shouldn't come as a huge surprise.
The game looks absolutely fine for an open world game considering the hardware the developers have been given.
