I hope that some of the eye-candy could be turned off. Like moving ailerons, elevators, flaps, muzzle flashes etc. The CPU hit may be non-existent but taking several of these little nuances away could give you as much 5 fps more. It doesn't matter wheteher you have 55 or 50 fps but on lower-end machines getting 20 fps instead of 15 makes a alot difference.
