anvilsmith: I am trying to play NWN on linux (Ubuntu 11.10), but find that the graphics are considerably poorer and the performance greatly drops compared to the Windows installation. Some textures are even missing, and this has nothing to do with haks.
It's the opposite here, on Windows and an ATI card with recent drivers "Environmental Mapping on Characters" make characters invisible and some textures of the Frozen Wastes of HotU don't appear no matter which settings are used (this seems to be a less-than-a-year old driver bug), whereas both work with the native Linux version of NWN and the latest proprietary ATI drivers.
anvilsmith: Whenever music is about to play (even at zero volume) I hear loud static for several seconds.
Sorry I don't know about that.
anvilsmith: I am not sure if the modified path is even the correct one, since there are two miles folders: miles_win and miles_linux (miles redirects to miles_win).
That's intentional, to make Wine find the good miles folder (e.g for the toolset)
The nwn script changes the link to miles_linux before launching the game.
