Hello guys. Last night I finally purchased my first FSX payware products, UTX and the Captain Sim 757 Block Bwhich I had been wanting for a while. They both seem to be FPS hungry for me. But my main problem is with the CS 757. When I'm inside the plane, I get literally 5 FPS. I can be in the middle of New York City or over the middle of nowhere at FL350, and still get 5 FPS. I thought it was that it's just FPS hungry, but when I took out all autogen, it still gave me the same problem. Can anyone help me? Anyone know what could be causing this? Thanks in advance.

My sepcs:
AMD 64 X2 4200 at 2.5Ghz
2GB RAM 800Mhz
GeForce 7950GT at 512MB
250GB HDD 7200RPM
