Hi all

I have a big problem when i run Crysis Warhead at Dx10 , Shadows are causing an problem that makes everything to Disappear, the only i can see is the eyes of the AI O_O
This is happening at The Enthusiastic Settings but also at Medium ! the problem is gone if i turn the shadows to Minimum or if i run the Game at Dx9 ... i have all my drivers Updated and also the Directx, i have not any problems like this in other games....

here is my system :

Intel Core 2 Duo 2.66ghz
Nvidia 9800gt 1 gb
3 gb Ram
Windows 7 32bit

i have checked Temps and are fine , also i have 30fps average at Max settings .....
so What is the problem ? :/
i Searched over google and found no solution.
