Anti aliasing it seems is possible wit ati cards in airborne, just seems that the game doesn't like it,
Title screen wont show any planes, the briefing wont be displayed, and when you're on the plane all you get is a static image with anti aliasing applied, even though you cna hear the game playing underneath all this, was able to jump out of the plane and fire my gun a bit even though all i could see was this:

Has to be some kind of a workaround for it though.
