Graphic Card?(Not the same thread as below)

So I play Modern Warfare 2. At the LOWEST possible settings in graphics and i still lag horribley. The only time i dont lag is when im in buildings. But the minute someone runs in this building, it gets super laggy.

I was wondering what it is.
I run Vista.
My Graphic card is NVIDIA GeForce 6150SE nForce 430.
Not sure if its very good.

Your graphic card doesn't meet the minimum requirements for MW2. The lowest GFX from the GeForce series you can have is the GeForce 6600GT. You may want to get MW2 Config (Google it, the one here is older). Click on the Graphics tab and drag the slider to Lowest and then click File > Save.
