You have a geforce ddr? that what i have. It might seem a little choppy in direct 3d, but thats the way it is in direct 3d in general. I've seen the game on several different cards, it always looks like that, it has nothing to do with the card or direct 3d.
The game isn't much of a stress on the cpu, it hogs ram though.
