Found new way to improve your Frame Rate

I bought a new PC and video card in hope to improve the quality of my gaming time. To my horror the quilaty of the game did not improve that much. I still had to reduce the sceneries Settings to low standards just just to get a decent resolution. I tried every trick I now and still when I played the difficult missions the frame rate would dropped dramatically. Well I remember reading that sound takes a lot of your PC capabilities. So I decided to reduce the sound output of my of my PC sound card and reduce the sound setting in the CFS2 program. Guess what ,I now for the first time was able fly missions at the maximum setting. WOW what
