I haven't tried a complete uninstall/install, but the intro looks impressive --- except --- When loaded in windowed mode and a custom screen size (I used 1237*1140) it breaks up into chunks that move forward in their frames independantly, giving a very broken up appearance. I tried to get a snap shot, but the result was to skip the remainder of the intro. The frame rates were in the 20s to 30s.

When I started the game in fullscreen mode, the intro was smooth for the most part, with only a few sequences where motion was just slightly jerky, such as where there was a large amount of uncoordinated motion. (where the troops were jogging down a hall, for example).
