My squadie has been having alot of trouble with his frame rate, it started close to when the new version came out. First his framerate will be 59 then in about 3-5 minutes later it goes down to about 4 framerate.It doesn't matter where he is even in the tower it turns into a slideshow of pictures.The framerate will do it over and over in a cycle, and when he's flying low in a plane it's even worse sometimes it stops still. I thought it might have something to do with taking away the cache folder?
