So I've got the GOG version up and running and I whenever I launch even a blank slate standalone module, the main menu theme starts playing like in the original post of this thread. That's not a big deal, but I seem to have a low memory cap severely limiting what I can do. I'm launching the editor from "C:\GOG Games\Divinity - Original Sin Enhanced Edition\The Divinty Engine Enhanced Edition\TheDivinityEngine.exe". I have 8GB of RAM which surpasses the listed recommended requirements, but whenever I launch a blank slate standalone module I see in the bottom left corner that I'm already at 19% with a cap of only 1690MB. When I try to create a 300x300 terrain as shown in the tutorial the editor runs out of memory & crashes. I can create a 111x111, but I reach the cap of 100% memory use if I do.

My searches on this website and google have been dead ends. Under preferences my Editor Data Path (C:\GOG Games\Divinity - Original Sin Enhanced Edition\Data\Editor\) and Game Data Path are correct (C:\GOG Games\Divinity - Original Sin Enhanced Edition\Data\). Am I overlooking something? Any suggestions?
