Yup I hear you on the crashes, so annoying that they released it like that, does New Vegas have similar problems? I played it quite a lot on PS3 and it seemed to have pretty similar issues to FO3.
No real issues for me with NV, except around lamplight or whatever it's called, in the south east part of the map. It's the big city that's completely irradiated and full of zombies, that would crash for me so I had to sneak around it to avoid crashes. Even knew exactly where it would crash and how close I could get it did it that often.
Those Crysis shots look great. Never played any Crysis game...should I?

Fantastic game and still very good looking in places, shame the lip synching lets the game down in the cutscenes but often the dialogue more than makes up for it.
