I have an ATI Radeon x700 Pro 256mb and for some reason my computer just can't handle Call of Duty 2. Its killing me, I want to know why. I've tweaked all my settings and no matter what my settings are, from normal to extra texture settings my FPS is choppy. I really like this game when it isnt choppy and want to play it on good graphical settings. Any reason for why this is happening?
