I got a resolution problem using the 1920x1080 files.
Patched the executable using UniWS (GoG version), put the files in the Overide folder, and started the game.
Main menu and settings looked fine, but loading screen and character creation were messed up, like they were centered around the bottom-right corner of the screen.
I can't post a screenshot right now, got some issues with my internet connectin, but I'll post the images here as soon as possible.
