Loaded up my save and it has such a low framerate that it is unplayable. Plenty of computer resources left in task manager. Normally after pausing (and going to a different window and back) or loading the game is like this for only 10-15 seconds, but this time it just won't go away. Disabling shadows solved the problem, but I've never had this problem before on this version. Is this a problem with my save, or something else?
EDIT: This only occurs in/near the base. However, I have never had this problem last long before and I am only using 66% of my total memory, with VotV only using 12%.
