Expotential, some planes have it but not enough. As for realism, i dont see how you can get any better, would you like to try my yak ? I have it setup for IMAC and 3D, it does ok imac, and awesome 3D. But, i think its kind of on the hard side of 3D, but it will sharpen your skills, it worked for me!!!! And it flies like an airplane.
