I’m curious if WoW is using any newer x86 instruction sets like AVX. I’ve been testing some math benchmarks on ARM emulating x64, and saw very little performance improvement with the AVX2+FMA builds, compared to the SSE4.x level. (X64 v2 to v3.) It was unexpected.

It’s the first Windows build with Prism and the first time they’ve introduced AVX(2) support, so I wonder simply if the performance isn’t there yet. I’ve found very little info online about this.
