When you guys complain about FPS what are your specs?  What texture max load are you running with what add-ons?  Have you taken the time to read on forums and do the few tricks to the fsx.cfg files as recommended in this forum?  I only ask because I run this plane anywhere with REX, ASN, UTX, GEX ect. ect. and get around 60fps in non-add-on airports and city's and 30fps in heavy add-on scenery's.  I"ll bet anything most of you having issues run 4096 max load texture, high road and airline traffic and max settings....with most if not all the add-ons listed above.  If this is the case, then it's not hard to understand that your straining your system.  I run 1024 textures using NVIDIA Inspector and I can guarantee you couldn't tell the difference....except the FPS lol.   If you use NVIDIA Inspector correctly that's what it does, but this is only 1 little small change you can make.  Take a few and read up "tuning FSX" in the AVSIM forums...it's all their and tested.  Hope this helps, Crash.

FWIW, I get crap fps with this bird and only have a max load of 1024 with zero traffic running and just REX as far as major add-ons.  However I do use it primarily in ORBX regions.  I also utilize nvidia inspector but god only knows if I'm using it correctly.
