Okay, I know I sad Bad Company Eats PCs for breakfast, but as is it turns out, NVIDIA was to blame, because I had installed the infamous 196.75, which caused many serious problems for GeForce graphics card owners all over the world. The drivers caused the cards to overheat and literally break down. As for me, I was cursing the developers of BC 2 (DICE), when I realized I had already installed the new drivers. As soon as I reverted to the previous NVIDIA drivers, the framerate returned to normal.

Just thought y'all should know.
