Thank you for your interest!

As for FPS, the Demo is a cropped version of the original 757 4.1. As far as some complex systems (FMS etc) in the Demo are "broken" so they do not load/work properly and might cause some overloads on some systems.

But I've just re-checked, even the "broken" Demo provides same or higher FPS than the competition 767/747.

As for the FPS of the original 757 4.1 please read the forum, you'll see that some people do have fps issues but some do not.
