I get huge fps drops on Modern Warfare 2. But Not because there's huge wars sometimes,i THINK its because of the driver i have, NVIDIA Ge-force 9100 it doesn't support DX level 11 and is not optimized for gaming, even though i received it in a update.

I hope someone has a answer or really good config. And i don't want an answer saying get a hardware upgrade, because im probably getting one later.
