I have just downloaded some scenery for Perth Intl Airport and i am very very pleased with it. But just one thing, i get a lowered frame rate wen im near it. Is there any fix for this?
Except your low frame rates did your graphics getting worst?.
Dont stay only to the number of frame rates.The first you have to look is your visual effects and your systems performance...if its getting slower,stucks etc.
Since we don't know your computer specs I can only guess that if you shut down some of the programs running in the background you'll get a better performance in graphic intensive areas.
Try this program and see if it helps you.
