I have that issue too, Fps dimisished sensibly, i tried the thing on the .ini, it didn't worked, in fact went even worse, and everytime i quit FL, the Widows admin panel detects it soaking CPU... not only that, each time you re enter into FL an quit, adds another CPU-soaking FL at the Win Administrator... while the game is quitted... everything goes alright when you force the end to the process from the pannel... al of this happens since last update:(
