I have problems with very jerky video - basically the game is pretty unplayable. I have a 2G AMD machine, enough disk space, 768Mb ram, NVidia GeForce something or other... Thought this would be enough.
I've tried reducing the quality (I don't really want to go 640 x 480). It doesn't seem to have made much difference, though I haven't gone all the way down to 1.
Any ideas as to how to get this to run better?
