Newer hardware does not equate to better performance if the game was optimised for hardware back in the late 00s.

Are you running it on Win XP or are you on Win 7/8? - if so there are config changes required for AF and probably for the Graphics drivers - it was barely supported on Vista even.

are you on the last patch (13) from Lead Pursuit?


Lastly you may wish to get the original Falcon 4 and try BMS 4.32 instead - released in 2012 its far more modern than AF.
