FL slowing down hugely

[Spacewolf]

Ok then i used to be able to have about 6-7 BS on the screen but lately i carnt even manage 1 player fighter. FL also slows down when ever a new type of npc fighter comes within 2k frezzes for 10 secs whenever i go though a JH. Randomly slows down when im loading the sever list. This is quite recent about 6-7 weeks now. Some other people have this problem as well and just so you know its not my comp heres the drives memory etc:
Graphics: Raedon X600
Memory: 2.98 free
and some other stuff thats way above the recomeded specs, any idea what it is?
