Hi, I just recently installed PMDG 737NGX on my brand new machine that I just builded for FSX, and I am experiencing a hugh drop (50%) in FPS when flying with 737 NGX. If I fly with the default 737 or any other, I have no problem with performance. I get somewhere around 12 FPS and I usally get 25 - 30 FPS. I just hope that 12 FPS is not normal because I understand that this aircraft uses a lot of CPU resourses due to overall detail of aircraft and systems on board. In addition, I experience other issues like CTD "fatal error message" when I end the flight - this happens 50% of the time. Also, If I go to map during the flight and whant to come back to the game, my screen gets all messed up, or if I have to go to desktop: same thing. I appreciate any help on this. Thanks.
