Larian Studios Forums Baldur's Gate III Baldur's Gate III - Technical & Gameplay Problems Massive performance drop after Patch 2

Same here, after patch 2 act 3 is unplayable for me dropped to 20 fps from 80fps.
No mod, all vanilla game. Same with DX11 or Vulkan.
Ryzen 3900X and 2080ti. My cpu and gpu use dropped in act 3 after patch, but only act3, other act run well.

I tried all workaround but nothing, only a rollback worked for me.
