Just play the Game FPS is bull all you ever want is smooth GFX and this game delivers
It's openGL so you can even run it without later windows resource hog.
The problem is the 60fps cap rather than smoothness, vsync on at 60hz/fps = horrid input lag, vsync off with a hard 60fps cap doesn't play nice with the update rate of the monitor giving lots of tearing which can be minimised so that it mostly imperceptible with higher framerates, but with a hard fps cap you don't have that option so sadly I've never been able to play through this game.
