Hello all,i have a serious lag problem with FSX in to a nice pc, when i start a flight it's ok, nice fps, but after a while i have 2 problems, one is the drop of fps slowly, in the cruce level not much, but when i'm approaching to the zone of destination, the fps drop considerably and i tested same position with a recently restarted pc and fps are ok and estable, second problem is when im on the cruce level or few minutes flying, not at the start, when i look around, the fps drop down horrible, but if i not move the camera, fps are very good, i find thats could be a sound problem because if i press "q" and deactivate all the sound, the fps when i looking around are very good, only in this second problem, i update all drivers, format hard drive, reinstall and nothing i think those problems not are a overtemp because playing my GPU around 70°, CPU 56° some times 60° hard disk and mother not remember exactly now but are fine too.

 

PC SPECIFICATIONS:

 

AMD Phenom X6 1055T

 

GeForce GTX 470

 

Memory ram 1600MHZ 64BIT 4GB x2 (8GB)

 

Mother ASUS M5A78L-LE

 

Hard drive ST2000DM001-9YN164 7200RPM 2TB

 

 

Thanks for any help

My computer will some resemblance to your:

Phenom II X6 2.8GHZ

Mobo M4A79XTD-EVO

Kingston 8 GB 1333

Saphire ATI-6950 2GB

Intel 180 GB SSD (Win 7 64, FSX, FS9, REX OD Plus, and P3D only)

HD 500 GB WD (other programs)

I do not have that kind of problem, you already experienced, quality change of scenery, autogen, clouds?

A detail, LM Prepar3D on my computer works much better than FSX.
