More polygons doesn't necessarily mean more lag. Like with the Outerra engine the world is made out of a ridiculous amount of polygons. You just need a good engine to process it.
That is what I was leading to...
I lead to it first
... Lag is from the amount of polygons on your screen (in some cases)
Of all the things that will cause low frame rates, triangle count is probably the least likely cause.
Minecraft has a debug info screen that tells you where most of the lag comes from. Usually it's from chunk updating (Like how Mythruna has leaf instead of chunk).
