As the title and description say. So far I've had some decent performance in the very first sniper mission where you sit atop the water tower. Then in the "direct hit" mission the performance was passable (when not around the main camp).
Then I got to the first main mission where you have to repel the enemy attack and the thing was a complete slideshow all the way through!! Not only that but half the time textures on the screen were reduced to their bare minimum level of detail until the more detailed textures were loaded in their place in rare instances (something which took a good 4-5 seconds).
My specs are as follows:
-Pentium 4 3ghz 800mhz FSB
-1GB RAM
-ATI Radeon X800XL 256mb
-Soundblaster Audigy 5.1 card
My screen resolution is 1024x768 and my advanced graphics settings are set at everything on low, except objects detail which is at very low. I've tried reducing the draw distance to 800m as well as disabling shadows and/or AA but that didn't help. I have the latest ATI driver as well as a pretty recent sound driver installed.
It seems the poor performance is occuring in missions near certain populated areas, or where there is a lot of activity going on at once. But then again that is not exhaustive because i'm sure I have noticed it in less populated/dense activity instances too. Some help would be appreciated.
