I had the same issue when loading Crysis. I also noticed a couple other games having the same problem. My solution was to use an older Display Driver. After that, the games load properly again.
Video Card: Radeon 9600 Pro
Installed: Catalyst Software Suite 7.10
Games: Won't load
Uninstalled: 7.10 Display Driver
Installed: 7.5 Display Driver (for test)
Games: Load
This issue was tested before and after a fresh Windows installation, so there might just be something with the new ATI software. I'm not sure really. I haven't had the time to test if anything above 7.5 works.
