You need to edit "CryRenderD3D10.dll" with HEX redactor

Crysis\Bin32\CryRenderD3D10.dll replace bytes value
from 5F 89 6E 14 to 5F 0F 19 00

Crysis\Bin64\CryRenderD3D10.dll replace bytes value
from 41 83 4D 58 01 49 89 5D 18 to 41 83 4D 58 01 67 0F 18 20

100% working with Crysis 2007
For Warhead I didn't find a solution like that!

I tried this and it worked perfectly.

I could not find these values in the current version of Crysis

This one really works!
