Normally in my game i get 125 FPS but after a little bit it drops to around 40-30 FPS and the audio makes some kind of static noise. I could play the game perfectly fine before but it is really annoying now so help would be greatly appreciated
My specs are:
Windows 7 Home Premium 64 bit
Intel Core I5 2430mb
6GB RAM
Nvidia GeForce GT 555m 2047mb
