Or not fly in Perfect mode, duh, which is just great water and somewhat better ground graphics mode. None which have anything to do with the overall gameplay.
It's amazing you can own the game, play it often, and not clue on the buzz words like "perfect mode". My friend flys with it but none of our other tournament ladder players do.
It looks good, but why if there is even a slight performance hit, or in this case, a patch bug, would you care?
How long you been in FB banana?
