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.
Arch Linux, Kernel 6.4.12
Ryzen 3900x
Nvidia 3090 w/ 535.104.05 drivers
Latest Proton Experimental
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 with 6800XT and 5800x3d. Same Kernel version.
