Low performance in DOOM Eternal

[VulkanGuy]

Doom 2016 Vulkan renderer is broken since 440 drivers ( Optimus )

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…

I think there is something wrong with those gpu’s on Linux driver. I also have one and has a weird problem that NV QA apparently can’t repro.
