Just built a new machine, Pent.4 3ghz processor, 2 gigs of ram, geforce 6200 video card and the game still runs poorly. I agree with BlackVoid, I was really looking foward to this game, but I am throughly disappointed.
Hmmm...I'm running the game itself, on a P2.4 with 1 gig RAM and a Radeon 9600 (1280x1024). XP pro SP2 and DirectX 9c. The only time I experience sluggish behavior is when I change the "Size" setting, then it's a bit of delay before the screen is redrawn. The tooltips do take a second to pop up, tho.
