Bug Report - Remnant 2 flickering glitches when using VK_EXT_mesh_shader

  • GPU: 4070Ti
  • Video driver version: 535.86.05
  • Kernel version: 6.3.12
  • Proton version: 8.0-104, GE 8-9, Experimental

Foliage flickers unless you run the game with VKD3D_DISABLE_EXTENSIONS=VK_EXT_mesh_shader, see video here: 2023 07 25 21 13 47 - YouTube

Since this game is UE5 and uses Nanite, this is probably relevant: UE 5.1 MAWI demo mis-renders mesh shader path · Issue #1632 · HansKristian-Work/vkd3d-proton · GitHub

The problem is still here with 545.29.06. When I try VKD3D_DISABLE_EXTENSIONS=VK_EXT_mesh_shader the game crashes a few seconds after start. I installed beta Vulkan 535.43.22 and it’s working with the variable. Without the variable it’s still flickers a lot.
