Hello There, I have noticed in games like crysis a steady framerate of 30fps is quite smooth. But in a game like Call of duty(any of them) when you drop below 60fps it seems choppy. I also notice that the reviews for game like MW2 say an average of 60fps is sufficiant for stutter free gameplay where In my opinion a Minimum of 60fps is requires for stutter free gameplay. What causes this severe change? And am I the only one who notices this in games like Combat Arms,Bioshock,Far Cry,Call Of Duty. I also notice that even though my monitor has a refresh rate of 60hz when I change my Nvidia control panel to advanced 3D settings instead of letting the 3D application choose anything below 90fps is extremely stuttery with any combination of settings. Any help with answering these questions is appreciated.
