I'm having a hell of a time running NWN for some reason. I run Vista, and it just lags terribly making combat certain suicide for me if more than two or three creatures are on-screen at the same time. I blame my video card drivers in combination with Vista. Until I can figure out a solution, I'll be AWOL for awhile.

Do you have an nVidia card?

If so, did you turn off Threaded Optimization for NWN?

That did it for me. My game was horribly laggy and it was due to this.

I do. I'll try that.

Err..where is this to turn off?

Try help and support and re-install game at a lower setting disabling visual themes. Helped for me.

Desktop > Properties > Parameters TAB > Click on "Advanced" > Gefore 8800 GTS (or whichever card you have) and then click on nVidia Control panel (You will need to install this if you dont have it!).

THEN;

3D Settings: Manage 3D Settings. At #1 box, select nwn.exe or nwmain.exe depending on which one you use. At #2, scroll down until you see "threaded optimization" And put it on OFF.

Cheers!

Oddly, I don't have that option.

The nvidia control panel?

You should normally have it. If you mean you dont have the threaded optimization option.. Look carefully, It isnt in alphabetical order I believe. Can you give me the model of your video card?
