I dont get it, what setup is the most maximum in options in graphic option?

Extreme

A question: The multiplayer demo version played very smoothly on my PC... does that mean I can safely buy the full version on my PC as well? Because I am a bit afraid that all that exploding and earthquaking will kill my computer. I am thinking of buying the PS3 version if my PC can't handle it. But then again the gaming experience will be a bit less enjoyable because I love FPS-aiming more with a mouse.

There's a pretty extensive list of requirements here if you scroll down a bit. Although it's already been stated that Crysis 2 won't be as brutal as C1.

Also, steam lists the minimum requirements as follows:

OS: Windows XP, Vista or Windows 7, with the latest Service Pack
Processor: Intel Core 2 Duo at 2Ghz, or AMD Athlon 64 x2 2Ghz (SUBJECT TO CHANGE), or better
Memory: 2GB
Hard Disk Space: 9Gb (SUBJECT TO CHANGE)
Video Card: NVidia 8800GT with 512Mb RAM or better, ATI 3850HD (SUBJECT TO CHANGE) with 512Mb RAM or better
Sound: DirectX Compatible Sound Card
DirectX?: 9.0c

Hope this helps!

Hope this helps!

Yes, it did! Thank you very much!

Ok thank you! But how to change these settings? I mean is there a custom way of changing settings? For example where i can choose "the number" of direct x(9,10,11) ? sorry 4 ma bad english

There isn't. Crytek (being the traitorous bastards they are) shipped the game with ONLY DirectX 9, and no options beyond the generic "system spec".

Damn((( I think it`s because consoles.....because they can 't make graphic much better on the pc than on consoles((( I don`t say anythink about the game, because i think i liked it even the graphic but it could be another breakthrough and innovation as the first crysis was in due time((
