I think it needs more than 32 megs of video ram. Your system is the same as mine, except I only have 256 megs of ram. I'm not going to even try it until I upgrade (2.8 ghz P4 and a 9800 Pro or something close to that). Plus, I hear upping some of the graphics all the way, such as the amount of foliage, really contributes to the gameplay

I wont play it until I can turn everything to high. There was a guy at the LCVG forums with a 9700 pro that has everything set to high, 4xAA and 8XAF and he says it's very smooth.
