Interesting.  Same as Tercio, am getting an fps drop from 25 to 12 in a standard (replicatable) situation with the C-130 loaded.   Shame, as love the model - it's just not too usable currently.

Will try applying SP2 and see if that makes the difference (was hoping not to yet, because of alleged impacts on scenery such as UK2000).

Will let you'all know if it makes a difference...
