I think this is one of most beautiful with everything vc,perfomance,well looking,i recenly bought a athlon 2g,64.8x video,512ddr and for me work perfect with all add on airplanes i have downloaded,and this majestic aircraft makes the display works in slow frames I even took off all the textures away and still .i took it from here URL http://www.fsfrance.com/Projets/Mach2/Download.htm
besides why the bad reputation? i read here from few folks "I Hate Concorde"

Oh,I see i was confuded,i though it was its performance for flying,i mean problem with *.air wrong behavior and things like that,i didn't realize it was for that kinda tecnical problems,in other words i thought problems just with the dinamic of flight and not technical issues
