I've got a question. Although I'm only experiencing it in this pack, I would imagine it's caused by a specific mod.
I'm using TDT 1.03 which contains TConstruct-1.7.10-1.7.1c Not sure if that will mean anything.
At idle, my game runs fine, and there are roughly 15-25 chunk updates happening at any given time. But when I start dispensing any metals from a smeltery, the chunk updates would jump to 160, and my framerate would drop huge, even my mouse would move slower.
So I found a hint that putting a smeltery in such a way that it crossed a chunk border caused this exact same thing. So i moved my smeltery into it's own chunk. Even the dispensers are all within 1 chunk.
Things have gotten a LOT better. Now the chunk updates only jump to about 80 while dispensing, and the framerate loss is barely noticable. But it's still there, and shouldn't be.
Are there vertical chunks as well? Is it possible I have the smeltery at such a height that it crosses a verticle boundary?
Thoughts? Ideas? There's no wrong answers when brainstorming.
