I've got a problem with my framerate in my 1.2.2 mod install (73 mods).
If I launch a rocket everything is good, but after e.g. 3 days in low earth orbit (SSRSS) , either in flight or from the tracking station, my fps are dropping to the half or more.
The longer the missions are, the less fps I get. My Moon Base is up there since 400 days and the fps are at 12 frames and it's getting lower.
Thanks for help
