I have played Divinity: Original Sin II for over 140 hours, and have always run the game at a constant 60 fps at default settings. There were a few spells I felt were underpowered, so I decided to try my hand at using the tools provided to modify them. So I followed a fairly straightforward guide to installing The Divinity Engine 2 and getting it up and running. I have successfully created the mod I wished to, but The Divinity Engine 2 runs on average between 5-8 fps. Before loading the level, and while loading the level, it runs 60 fps, smooth as butter. But as soon as a level is loaded in the fps drops. While I've been able to get by so far, as I've only been using the Stats Editor, I'm tossing around the idea of starting a game as a DM for me and my friends, and I'd like to create some custom levels. I don't see how I could really accomplish this with the current performance. I searched online for a few hours and only found one person who seemed to have the same problem, and they posted on the Steam forums and they never got a proper answer. I would be very grateful if somebody was able to help me and figure out why I have such poor performance.
Specs:
i5-4670
16 GB DDR3
GTX 1060 6GB
Don't think any other specs will matter but if they might I can provide more. I have the game installed on a 7200RPM HDD, but if it is the reason for low performance I can transfer the install to my SSD.
