It's only detecting your Intel GPU, so you probably don't have the RADV driver installed or it doesn't support that GPU for some reason. So, you are in fact not using your AMD GPU, and on the Intel driver it fails to create a depth buffer for some reason.
You can verify that by setting DXVK_HUD=1 btw.
You are totally right, because when I run Rise of The Tomb Raider, it shows Intel Haswell Mobile with Vulkan, and this game is a native game not running with Wine.
Thanks for you reply.
After searching for a solution for a little while....... Finnally, blocking Radeon from grub fixed my problem.
The updated instructions is in the info of this video :
DXVK_HUD=1`x1 2018-06
System information
When I try running The Witcher 3 Wild Hunt, it takes forever to load, and I have to kill it by myself.
I use DRI_PRIME=1 to ensure that the game is using my AMD GPU, and mesa-vulkan-drivers are installed (Padoka stable).
