in many respects this sim be inferior to fs2004 . the frame rate be terrible and the aircraft viewpoint too fussy to get to quickly . anyone with fs2004 and with good add on scenery I would advise to stay with it . my computer be state of the art with dual core pcu , Nvidea 7900GT graphic . over New York in fs2004 with all slider max out I get over 35 fp , with FSX I get 7 fp . with slider at normal and a slide show . I have since uninstalled my FSX and return to fs2004 .
