I have this problem aswell, I recently bought an Nvidia GeForce 7600 GS Graphics Card (so I can play 3D games). Works great with all of the 3D games I've played so far. On Graal it doesn't work well at all, my movement is slowed to the point of almost not being able to play. I cannot do any of the things I use to, basically enjoy the game. There's a long pause at level changes and very slowed movement in an area with high population.
