The Captain Sim C-130 is my most favorite add-on aircraft. The FSX version has a few minor qlitches that I'm sure CS will fix. Frames Per Second (FPS) is a serious problem.  I live in the Dallas/ Ft Worth, Texas area.  Take off from any airport and FPS are in the single digits, very herky jerky and completely unuseable.  But once I leave the DFW area FPS jump up to 25-50 (set at unlimited).  At high altitude (27,000ft) over the country FPS are anywhere from 40-80, smooth as silk. Fly over DFW at 27000ft FPS drop to 15-25.  Fly over DFW at 5000ft and FPS drop back into the single digits and becomes a slide show. Leave and fly back out into the country and FPS jump back up to higher FPS. Same for Seattle, San Francisco, Los Angeles, Washington DC. and any other large congested area with lots of autogen and dense scenery. The C-130X is a great airplane as long as you stay away from large dense autogen areas such as big cities and airports. I'm still glad I bought it and will stick with it until Captain Sim gets all the bugs worked out.  Hopefully soon? My autogen is set to very dense and scenery complexity is set to extremely dense.  Could that be my problem?

Yes, your auto gen and scenery complexity is your problem!  It's not the C-130.  Don't compare your C-130 frame rates to your stock aircraft frame rates.  If you have any add on aircraft of similar quality and size from any publisher you will see the same results.  Don't compare your C-206 frame rates to your C-130 frame rates, I am absolutely positive that the C-130 is much more complex with animations and other sorts of things than the C-206.  Autogen is the biggest frame rate killer.  Yes it's nice, but it is the most enormous resource hog!  You have got to take that down!
