OpenGL support is more of a personal pet project than something vorpX does ‘officially’. It’s limited to fairly old fixed function versions of OpenGL. Anything that uses shaders won’t work.
Never tried it, but rjkole’s profile is likely for the original version of the game, not the EE. Should still be available on GOG, not sure about Steam.
Damn, that’s a shame. I figured it was something like that. I was mainly looking to take part in the persistent online player-made worlds in the game but sadly, it seems that the new version of NWN is the only one that still supports that.
Ah well, thanks for the clarification in any case.
