Ok so, I've been looking around here and another forums for a day and can't seem to find a solution that works.
When ever i try to run the game it "starts" and all I see is a black screen, No intro videos, nothing, nada. I cant Alt+Tab out, I cant Alt+F4 and no Ctrl+Alt+Del. It's completely locked. All I can do is to power off my computer all together.
I have all the latest drivers I can find. I'm at a loss here...
I bought this computer in December because of this game and a few others. It can run it!

Has Crytek released a Supported Cards, not supported cards comment?
Ok computer specs then.
Windows 7 64bit
Ati Radeon HD 5850
Intel Core i7-875K
RAM 8G

I played the Demo just fine by the way, no crashes, no lag, nothing.
If anyone has any idea what it could be, please help.
Thanks in advance. =)

Bump. Still no go after trying some different settings on my video card =/

You would be better off contacting customer support than posting this here.

Ay, I'll give it a try. It's just that the community usually know what to do or try, and even more so when it's a PC game that doesn't work.
And the community in general is usually the best option in my experience, and the quickest =)

Ok I haven't tried custumer support yet as I am way to tired to go through that process.
What i decided to do though were play through warhead to refresh some story and what not... So i intalled it AND I GET THE SAME BLACK SCREEN AT START UP!! Wtf? O_o That never happened on my old computer... Bought this one in December if I didn't mention that.

Looking through the Gamelog for both warhead and Crysis 2 i noticed one little thing they had in common...
Is this line "Current display mode is 1360x768x32, (Unknown graphics card)" Im starting to get the feeling my graphic card is the villain here -_-

A small update, after installing the 64bit version of Warhead it now works...
Annoying.
So I cant run 32 bit Crysis 2, I cant run 32bit Warhead on this computer then... Question is do I have to wait for Crysis 2 64bit version to be released before I can enojoy the game?
