I have a mediocre computer, yet I can crank up every setting to its max (except when I'm flying the 707, then I have to turn off traffic, but that doesn't really matter) and enjoy frame rates over 20 even at large airports. Albeit, my graphics aren't as stunning as pj747's pic, but it's called a flight simulator game for a reason, and that is that it's not real-life, and so it's not perfect. All I can say is I hope you enjoy Flight when it comes out.

Cheers,
