The views are stunning and the graphics generally look very good. The only bad thing I noticed is that vegetation in some places looks terrible. Like here:
Those clumps of grass look really pathetic. It looks much better in some other areas so it will likely be fixed in the final version.
Now onto something positive: the lighting is simply beautiful. I think I've never seen better day/night transitions in a video game. And all the other light effects look just as amazing. And my God, that rainy night in Lucis
Damn.
