Both Nvidia Control Panel and ATI Catalyst Center have options to force or override graphical aspects in any program; he's talking about the vsync override, which basically is set to always, never, or leaves it up to application specs. Vsync is the synchronization of frames per second between the video card and the display you're using (monitor, hd screen, etc.) I don't know, however, if such fixes the scrolling issue you mentioned. The only thing I can ascertain is I had an ATI HD3870 which gave me lots of trouble with NWN and many other games (it actually died because of baking), and I've had a GTS 250 Twin Frozer which ran perfectly, as well as my present GTX 285. Maybe it was the model, maybe it was luck; whatever the case, I won't buy another ATI card ever again. People say the shinny water-lacking is not important but I will say this: Nvidia got word from players NWN wasn't running correctly on new cards, and they fixed it, even though the technology is going out, the game is old, and there aren't that many gamers playing it. The shinny water issue was reported to ATI and they placed the blame on Bioware, refusing to make any fix. I won't support a company like that, specially when there's another with a long history of quality products.
