Game gets sluggish when using some add-on aircraft

[pg8841a]

Hey everyone, I've been having some trouble running a few add-on aircraft in FS9. The game gets incredibly sluggish when I fly these planes, but as soon as I load a different plane everything works fine. The two planes that seem to really cause problems are the Ameristar Air Cargo 737-200 file name ajib732.zip and the Mozambique Airlines 737-200 file name 7372moz.zip. Has anyone else experienced similar problems? What can I do about this?

Thanks, Paul

No probems here with any of the the 737`s available, and i can even run the pmdg fine , but for some reason every A320 i download i get really bad fps , i dont know why because i can run PSSA340 great. I dont mind because i like 737`s much more than the A320. NORTON

Heh, I have the exact opposite problem. Not making it up, I have excellent framerates on the A32X series, but the 737s take a while to load. The PMDG 737 was a nightmare... it's not on my system anymore. But then again, I get great FPS from all the iFDG aircraft.

Some add-on aircraft use more individual parts (polygons) and/or more detailed (larger) textures than others, so they can cause a performance hit, especially on lower powered computer systems. Panels in use (including virtual cockpits) can also add to the load.

My solution is to save aircraft that I otherwise like but that give me performance problems for my next computer (some time away yet).
