I have been doing putting in extra time with my Nvidia drivers, since I needed to, [ArchiCAD was freezing during copying, http://www.graphisoft.com/support/archicad/archiguide/UsingMenusFreezing.html] and have come across this website/forum run by some folks who really seem to know their stuff. If you are using Nvidia cards, especially in a laptop check them out at:
http://www.laptopvideo2go.com/
Their enhanced .inf files offer an expanded adjustment/control of your already powerful video card, and the forum administrators are cordial and helpful.
