Low FPS :(

[TR.KARA]

Hello everyone.
Here is my pc features;

Q8400 processor
4GB ram
Nvidia 1 gb 9800gt 256bit graphic card
and I get 15-30 fps especially in Insurgancy maps. Is that normal in my opinion this fps is very low and I playing in full low settings. I check the temperature while I playing cpu is max.58, graphic card 40-45, motherboard 40. Is this fps is normal ?

Not a joke, try running the highest settings. Sometimes people get higher FPS then.
