I have a 9600M GT and 9400M. I am playing on the 9600M GT and I have configured my settings so I should be getting a smooth 30-40fps constantly. It is "fine" if I stay in one spot and not move the camera. By "fine" i mean that instead of constantly bouncing between 5 and 50fps it bounces between 20-35. By this I mean it will go up to ~40 then drop down to about 5-10 then bounce back up to 40. This is completely regular and no introduction of more effects or activity seems to change this.
I have the latest graphics update installed, and turning the settings down does not seem to change the fact it still does this. Is there some setting I am missing that fixes this? I am running natively at 1440x900 and don't want to change that unless it is the only way I can make this playable.
Any suggestions or recommendations as to how to fix my frame rate issues?
