Here is a dropbox link to a modified NAS Alameda based on Dimus observations though he couldn't fix it. With those rec's I changed and remade a number of buildings so that the airport would be gentler on the fps's. The wrecking ball has leveled the NEX Gas station and a small FSX self-serve is in its place. The commissary is also closed so you'all have to go to Piggley-Wiggley. LOL. I STILL have no problem in my FSX(A). Yes I DO have slower fps off and on but I get between 10 low to 37 high consistently on the ground even with a MJ C47 V3 on the tarmac. Better with this "Simple" version.
I'm not saying you guys don't have a problem that would be silly so I spent the afternoon and this evening trying to fix it for you being stuck here with a lousy cold. Here is the link. Please lmk here if you still get minus fps's or OOMs with this one. I have not gotten an OOM since I switched OS to Windows 7 64bit from XP 32 bit. My system is a Dell desktop with Intel CORE2 CPU with 2GHZ 4GB RAM and an AMD Radeon HD5450 video card. Certainly not a state of the art system by today's standards. I am currently set to Uichi's standards in FSX which I included in the Final Version Folder.
