I am very sorry. But I made a big mistake. It turns out that the areas I was in did not really use Physx as much. Then I went into this other area where they had alot of Physx effects like steam and smoke, and bam, my FPS went down to 10 and the game as alot slower as well.
Very sorry once again.
It looks like my system was able to handle the dynamic paper, and interactive objects, but not the smoke.
