So I thought i'd make a new thread, considering the full game is out and I just finished it.
Bottomline, these are the best graphics we have ever seen in a game. Using the dx9 tweaks posted on the incrysis forums, I was able to get between 20-40 fps with my GTS SLI (they require the new beta drivers to work). This corresponds to the ultra high settings give or take a feature here and there
The action is intense at points, and the freedom is breathtaking. At any point during the game, a situation might happen thats totally unexpected and makes you boggle at the engine. For instance at one point I was in deep trouble and running behind a car for cover when I run face to face with a guy. I grab him by the throat and throw him. Except he lands on a landmine and proceeds to explode several others nearby and the nearby building caves in and kills the people who were picking me off). There are many other things like that (like when a helicopter blows up and the carcass falls down on top of me killing me outright).
Story is good, its a tad short depending on how you play it, but worth every second of it.
The AI is pretty solid, the only thing that irratates me is how many shots it takes to take a person down (tweakable of course, but it makes things too easy).
I've had several bugs while playing, probably due to the beta drivers. There is a memory leak that restarting will cure, and sometimes sound just randomly turns off (also a restart). But yes, several points during the story you will see visuals that are so night and day diffferent than anything you've ever seen, its worth it for that alone.
