I have a P4 2.8Ghz 1.5GB Ram 2 Serial ATA drives Striping for faster access and a Nvidia Geforce 6800GS.
Runs smooth in demo until the shooting starts.
Have turned down the settings and still is slow. I have to pause game every few seconds to have some control over what is happening.
Hopefully this will be sorted soon.
Maybe I need to invest in more RAM.
