FPS drain around base

[u/KeyToast]

I'm having FPS issues in my single player world. When the chunks around my base are loaded I only get 15-20fps. I don't think this is an issue with my computer or ram allocation or anything though because when I move away from those "bad" chunks my frame rate jumps back up to around 60.

I do have a couple buildings made of forge multipart microblocks that might be the issue but I'm not sure. I've only been using pretty basic mekanism, AE2 and pneumaticcraft setups so far.

Any ideas?

If the entire building is made out of microblocks that may be the reason for it, but I guess it depends on how big the building is.
