Tip for getting Neverwinter Nights to run on modern Windows systems using AMD Radeon hardware:

On Windows 7 and newer OSs with AMD Radeon hardware, when the game is launched it will immediately crash. As strange as it may sound, if you encounter this problem go into the game's installation folder and rename the game executable to something else and run the game directly by launching that executable instead of using the start menu shortcut or GOG Galaxy. Alternatively if you would like the game to launch properly from GOG Galaxy or the shortcut, you can fix them up to launch it also.

Step 1: Rename nwmain.exe to nwmainAMD.exe or some other name of your choosing.

To fix the game shortcuts:
Step 2: Find the shortcut on your Start menu, desktop etc. and right click and go to properties, change the executable name it is launching to whatever you called the new executable in Step 1 above, then hit ok. The shortcut should now successfully launch the game.

To fix the launcher in GOG Galaxy:
Step 3: If you installed the game via the standalone installer, it will not show up in Galaxy by default as the installer is not Galaxy aware after 2 years, showing how much of a priority it is for GOG to have all games integrate with Galaxy to make life easier. You'll have to manually import the game yourself by finding it in your library and clicking on More->Manage->Import and pointing it to the game's install directory then waiting for it to sync. If you installed the game using Galaxy, you don't have to worry about this.

Step 4: In the game's installation directory you will find goggame-1207658890.info now, edit it and look for the section flagged "isPrimary" which has a line pointing to "nwmain.exe". Edit this line and change it to whatever you renamed the executable to in step 1 above. Do NOT change anything else in the file as the slightest typo or error will result in the JSON parser rejecting the file and having to reimport the game. Save and exit, then exit and restart GOG Galaxy. The game should now launch from Galaxy when you click [Play] without any problems.


FAQ:
Q) What the??? How can renaming the EXE file make a non-working game work???
A) I'm afraid you'll have to ask the AMD/ATI video driver development team why they detect the filenames of the executable files of certain video games and fuck them up so they don't work. Renaming the file makes the AMD driver not detect it and not fuck it up. Yay AMD!!!

Anyhow, it drove me f'ing nuts a few months ago to figure this out and there's a good chance someone else might encounter it so I thought I should share the info here to save people the headache. :)

If there isn't, I could import the game into Steam and launch it that way so I can broadcast the game using Steam video broadcasting, however people would of course only see me, which probably would either not be too interesting, or would be very hilarious since I have almost no experience with the game and am likely to get slaughtered. LOL I only played it for a few hours a couple of months ago during some beta testing and only made it through the beginning of the game which acts more or less as a tutorial. I never got to actual fighting outside of the initial village. :)
