Yes I read that in May.
I have a i-9 12900K so that does not really apply to me.
This issue I saw in the original launch week and then they patched it out. Since then I have not seen it till this last patch.
Turning off the RT and Res Scaling, which I have done in the past and Blizz insists on turning it back on with every patch…because it is so awesome from their POV, made the issue disappear for the most part.
The problem is their code. Turning all that off just reduces the game’s chance to hog more resources, but it does not solve their issue.
Do appreciate you digging that up to be helpful it may help someone else.
