This is the only thing that works for me: disable DX11 in-game through the menu. You can leave the rest enabled. Yes it means we have to do without DX11 - still - but at least we can play. Please confirm or deny this as a working bypass.

I'll try enabling DX11 again tomorrow and see what happens. Game crashed twice right after showing some artifacts, and miraculously recovered itself the 2nd time. And no; it's not a GPU or temp problem.
