No change
But thanks for trying. I'll play game with my desktop computer with XP on it. Problem is I need plug peripheral devices (like speakers and mouse) back and forth between desktop and laptop.
[edit]
It seems turning graphics to CPU will cause same problems with my XP desktop as has been described with Win7 laptop. I had to uninstall and reinstall game to get it back to working 3d. Also I had to stow my laserprinter to closet in order to make room for 19" CRT on the table becouse game graphics flicker on LCD monitor.
