Any way to lessen the impact clouds have on my FPS

Hey guys, haven't had any leisure time for awhile due to being swamped with schoolwork. Got to play some FSX today finally.
Anyways, I start to lag incredibley whenever I put on my clouds, and it seems to be the same significant amount whether they are 3-d or just simple. The density doesn't make a difference either, they just kill them though. Thanks for the help ;D
