[Metatron]

Lately my game randomly slows down, but the strange thing is that it doesn't seem to be dependent on the number of planes, objects etc.

For example I might be on a map with 20 aircraft flying, and everything will be running smoothly,
and other times the game goes into spastic mode when I'm flying on my on, on the Smolensk map in QMB.

Any ideas what's to blame?
