Patch 2 seems to have drastically slowed down the Vulkan Renderer. Before I was able to get 80-110FPS in the Druid Grove, but now I am only getting 50fps. DX11 seems fine though, but I prefer using Vulkan since I am on Linux.

I had issues with the Vulkan renderer on W11 as well. DX11 works fine for me on both W11 and Fedora38. Getting around 200FPS max settings at 1440p in the groove.
