I'm following DW20's Let's Play season 8,and I've built an Immersive Engineering area, more or less similar to DW20's version. I'm wondering if anyone else is experiencing lag which seems related to certain IE machines? I've been finding lately that, when I'm in the vicinity of a part of the IE area, the game gets really "sticky", with FPS ranging from 5-120, It much worse when I'm around the Cloches / Arc Furnace -- I have Metal Presses there too, but they were there early on and gave no problems then. Lag really only became a playability problem when I increased Cloches from 3 to 6 (2 Melon, 4 Hemp) and added Detectors (RefStrg) to prevent overproduction by Cloches. I needed more Melon/Hemp because I needed more Plant Oil & Ethanol (2 Squeezers, 2 Fermenters) to keep the Refinery adequately supplied. The system, and the control, are working fine - indeed all the IE Machines work correctly. It's just severe stuttering, stickiness, lag, which renders the game unplayable when I'm in that area.
