There's a bug in beta 1.3.3 I'm currently running Windows 10 on a core i7-7600U; steam client. Currently in winter; when I go to my home base, and it turns to night, or is night, the frame rate plummets to 1-2 FPS. Not sure whether it effects other seasons or not. It seems to get worse the more things are on the screen, i.e., when I have my 20 kegs moving around in view, it gets worse. Leaving the area, like going into the house, or going to the north, or south, or east, resolves the issue. FPS is fine. It's only the home area, at night.
