I have Windows 7 beta 1 32 bit on a Core 2 Quad + Geforce GTX280 with 181.22 whql drivers
Crysis Warhead crashes systematically after the loading of a level in dx9. In dx10 it is OK.
Do you experiment this crash as well ? What do you thing is the cause ? The drivers ?
Other games I tested works OK. Crysis 1 works OK in dx9 and dx10.
