Also, if the frame rate drops below a certain number, it's probably to do with the flip true you will most likely have. Try flip false, and the frame rate should stay more stable.
I'd go with Wolron too and suggest the number of collisions your using, maybe even the number of surfaces might have an effect too. Try and combine them using addmesh or something :o)
