Hello all, like it says on the title i'm getting random FPS spikes. It all started when i got the Quality wings BAe 146. I loaded up at EGLC (London City) and noticed my FPS going from 30 down to 1 or 2 every 5 seconds. I deleted my config file and started a new one which didnt fix the problem. I then uninstalled the plane and problem fixed. Today, i installed FSdreamteam O'Hare and i'm getting the same thing! Except this time I don't have the plane installed. I'm getting 30 fps the it drops down randomly for no reason. What can I do to fix this?

UPDATE: This problem now only happens at FSDT Chicago, i test at other airports and no problems. Also, the demo was fine, no problems...
