Sweet!
Works great on my Win7 x64 ATI build.

For you nvidia people,
Quote:
1) Install nvidia driver
2) Install and start nvidia inspector 1.93.
3) Go to the driver profile settings (or start in advanced mode with this cmdline: nvidiaInspector.exe -showSettingsOnly -enableSettingScan).
4) Search for the Falcon 4.0 Allied Force profile
5) Click the button that says "add application to current profile" (small icon of a window with a plus-sign
6) Add /FreeFalcon5/FFViper.exe to the profile
