@ spick: can you recall when you installed nwn if it ran a compatibility test or something like that? it should. if it didn't, i think your copy is the problem.
also, what is yor vid card? i read somewhere in the bio forums that nwn seems to run fairly smoothly on nvidia cards, but not on other cards of comparable power. i only have a geforce 2 (thought on upgrading but held out for the meantime as i think prices of nvidia cards may fall further because of nvidia's recent releases) and 256 mb of ram and i hardly encounter any problems, except for some slowdown when enemy mages rain on spells like they're throwing confetti on a parade. well, at least my monk is still standing there barely injured despite all kinds of spells being hammered at him. ahh monks, supreme mage-killers as they are... <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
