the strange thing is : when i'm not combating with enemies,even if there is many clouds , the FPS is not low (about 30). the FPS goes down when I or friendly aircrafts contact with enemies.

I am playing "lock on flaming cliffs 2.0" , when I get into a fighting in some of the missions ,the FPS goes very low (sometimes 1~5 !). When fighting is over ,FPS recovers to 20~45. I also have decrease Cloud Density , go to graphic settings and set everything to LOW and turned off everything but there is no change. So how to solve it? Please help . Thank you!
