After you have tried the link above and see how it works on your system I would consider building or purchasing a new desktop. Probably 4 years ago I was using a Dell Inspiron and I wouldn't try to run FSX and add-ons on that laptop. I am currently typing this reply on a Dell XPS M1530 which I used to run FSX on. No add-ons. It worked fine with no add-ons. Since that time I acquired a desktop with the specifications listed below. That was last November that I got the current system and I sure technology has past it by now. I only use it for FSX and add-ons which I run in the full screen mode. For everything else I use the Dell XPS. I hope the Bojote site works for you. The CS planes are around 35-45fps at cruise altitude and 15-20 at add-on airports The MD-11 runs at 95-110 and 25-35. The FSX default planes, 744, and 748 I have never checked to see what FPS they run at.
