I was able to play this game with Vulkan renderer at 440 series drivers just fine. But with 450.66 driver and newer releases (i’m on 455.45.01 now and problem still exists) it has visual corruptions all over the place. Game doesn’t have any of those mentioned/shown issues with OpenGL renderer and id Software’s embedded performance metrics shows with OpenGL renderer driver reports VRAM as 4096 mb like it should be , but with Vulkan renderer it reports 4342 mb’s of VRAM.
I’m running the game via SteamPlay/Proton 5.0 on an Optimus laptop with these variables:
__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia __VK_LAYER_NV_optimus=NVIDIA_only steam
Nvidia bug report and screenshot that shows the issue at main menu are attached. Also video footages that shows the issue are also attached.
