You see, it is statements like "you can't fly heavy aircraft in FSX" and "I need 40+ fps to be flyable" that are just not credibilty enhancing.  Generally, if you want to argue, you get further by coming within shouting distance of reality.

There are ways to get good performance in FSX and fly heavy airplanes any way you want, but it would obviously be a waste of time to discuss them in this thread, which is indeed pointless, or, rather, has a point that is a waste of time for most people.
