Adding my story. I am also experiencing the AVX issue. I bought my computer in 2010 to play Starcraft2. Made several upgrades since (2 vid cards, ram, hard drives). Haven’t had a reason to change out the CPU/mobo. My computer still holds up to modern games on modest settings like the new Doom series.
I don’t understand why I don’t meet the min reqs for a remastered, 20 year old game. I’m sure a lot of people have similar situations.
Blizz should definitely fix as a priority.
