So I've been testing the 1.10.2 port. For some reason in singleplayer, I can't get a new world to load with-in 20 minutes (at that point I just gave up). If I remove GT5, I can create a world no problem.
If I save that world then exit, then re-add GT5, then load the previously made world, I can play and generate GT ore as I move out of the initial start area. But this initial world start lag is a problem. Is this happening for anyone else? And is there any steps I can take to figure out if the problem is on my end? Or any performance tips in general?
