Yeah, that's exactly my problem too. It's weird that a search for "Black Textures" didn't find that thread.
Anyway, none of the solutions posted there has worked for me.
Yes, I have changed the texture resolution, I have verified the local files, my laptop does not have integrated graphics, and reinstalling the game to a different location (C:\TEST\DivinityDC) or changing the user didn't work.
I'll wait until to Monday to email. Probably no point in bothering them in weekend.
Thank you for your response.
