FEX-Emu Is Working On Speedy x86/x86_64 Games Support On AArch64, Including Proton

Not to be a downer, but how is this supposed to handle some of the more complex instructions like AVX2 without totally butchering performance?

By and large, AVX2 instructions aren't "more complex", they just use more register space. If there exist equivalent sized registers (or enough smaller ones) and similar instructions on your ARM target, then they get translated like any other.

Actual complex instructions have an advantage in translation, because templating/expansion is easier than consolidation.

So I am a bit confused, is FEX-Emu meant to work with Apple's M1 hardware/sillicon based x86 virtualization or not? From the contents of the article this appears to be a generic solution?

it's standalone, generic solution, like box86
