Well this sure is funny.

People,Yesterday I upgraded my system from an Intel Dual Core 3.0 ghz to an Athlon X3 445 3.1 Ghz on an AMD Chipset.I did an Overclock to around 3.7 Ghz stable and then I reverted back to my 3.1 Ghz and actually now I do not remember the settings. When I Oc'ed to 3.7 with other changes I got a tremendous boost in FPS from 20 fps to straight 40-60 fps and all high sets.So after I reverted back to 3.1 Ghz definitely FPS dropped quite low , then I went back to 3.7 ghz but as I do not remember my settings I am not getting those 40-60 fps.Now here is what is funny, I have installed NL-2000 scenery , here I don't get anything above 15-16 fps but when I fly at KLGA (NY) I get 17-23 fps and sometimes 29. NL-2000 does not contain much 3d buildings. Where NY is like full of 3d buildings.I have not tweaked my fsx.cfg for the new installation, I have the FPS limiter but no difference.I AM SCRATCHING MY HEAD.
