I've had a lot of issues using my computer in windows 7 that never happen when I have begun using Ubuntu on the same computer. Usually the game just freeze, sometimes, everything looks like a winter landscape with no color on the textures the seconds before the crash. I've thought it's something wrong with my computer and never really thought about it, just restarted the game (and died a couple of times doing it). But then, I tried Ubuntu and played NWN through Wine and realized that the game never had any kind of problems, and that made me think that the problem was connected to windows and not to hardware or NWN. When I got some help to check the "log7lofile" the error was connected to the file: atioglxx.dll

My specs (I have the newest drivers for all software):
win 7 home premium 64 bit

Graphic card: ATI Mobility Radeon HD 4650, drive 8.634.0.0
Catalyst™ Control Center-version: 2009.0729.2227.38498
(I have updated to the last drives of the ATI card though there seem to be an 11.12 version out, but it isn't aquired when I hit my "update" button on my pc)
Memory, ghraphic card: 1024 MB DDR3
Direct X: 11

Maximum specs in NWN except shiny water, played in full screen mode.

Has anyone else gotten this kind of trouble in NWN and found a solution to the problem?

Start win7 without ati CCC. Fixed texture issues for me. There are install scripts to run nwn native on ubuntu (ppa:nwn/ppa).

I know that there is a native Linux client, I have tried to use it but failed. That's why I use Wine in Ubuntu. (http://www.amiaworld.net/phpBB3/viewtopic.php?f=2&t=62939) . Anyway, after a lot of struggle, I updated to the last ATI Catalyst version (v. 11.12) and the problem seem to have disappeared. Don't lock the thread yet though, I haven't been around with a party, just solo, and it used to freeze more often when a lot of animations happen at the same time on screen.
