The machine and graphic setting (and maybe enviroment setting) may be greatly different from my x-plane. I have a kind of powerless PC and not playing with full graphic options. I think the fps you normally get with a default airplane ( like CL415, cirrus jet, L5 or cessna172 in 3D cockpit) in specific area and sky condition (maybe default sky in demo area?) would also be a cue to know what performance others will get with this beauty. Comparing with other plane is easier, I think.
