All I know is I'd like to be able to play NWN 2 but the camera is extremely frustrating. I would think someone would have made a mod to help with the camera. I've never tried to play a game where the camera was such a pain in the butt.
I play mostly in Character Mode, you could try my settings by pasting them in your nwn2player.ini
[Character Mode Options]
Show Move Cursor=1
Mouseover Highlight Flags=74
