Vulkan
From wikipedia:Vulkan (API):
- Vulkan is a low-overhead, cross-platform 3D graphics and compute API.

Installation
To run a Vulkan application, you will need to install the vulkan-icd-loader package (and lib32-vulkan-icd-loader if you also want to run 32-bit applications), as well as the Vulkan drivers for your graphics card(s):
- Intel: vulkan-intel (or lib32-vulkan-intel for 32-bit applications)
- NVIDIA: nvidia-utils (or lib32-nvidia-utils)
-
AMD: there are three implementations, which could be installed simultaneously:
- vulkan-radeon (or lib32-vulkan-radeon) - RADV (part of Mesa project)
- amdvlk (or lib32-amdvlk) - AMDVLK Open (maintained by AMD)
- vulkan-amdgpu-proAUR (or lib32-vulkan-amdgpu-proAUR) - AMDVLK Closed (maintained by AMD)
Other drivers may be installed manually instead:
- PowerVR: https://imgtec.com/vulkan
- Adreno: https://developer.qualcomm.com/software/adreno-gpu-sdk/gpu
For Vulkan application development, install vulkan-headers, and optionally vulkan-validation-layers and vulkan-tools (you can find the vulkaninfo tool in here).
Verification
To see which Vulkan implementations are currently installed on your system, use the following command:
$ ls /usr/share/vulkan/icd.d/
Vulkan Hardware Database
The Vulkan Hardware Database provides user reported GPU/driver combinations. Supplying own information is possible by using vulkan-caps-viewerAUR.
Troubleshooting
Error - vulkan: No DRI3 support
If you get the message above and using Intel graphics, you may need to force DRI3 and restart Xorg:
/etc/X11/xorg.conf.d/20-intel.conf
Section "Device" Identifier "Intel Graphics" Driver "intel" Option "DRI" "3" EndSection
Nvidia - vulkan is not working and can not initialize
Check if you have vulkan-intel installed, it may prevent Nvidia's vulkan driver from being detected.
Alternatively set the environment variable VK_ICD_FILENAMES
to /usr/share/vulkan/icd.d/nvidia_icd.json
.
No device for the display GPU found. Are the intel-mesa drivers installed?
Try to list both the intel_icd and primus_vk_wrapper configurations in VK_ICD_FILENAMES
export VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/intel_icd.x86_64.json:/usr/share/vulkan/icd.d/primus_vk_wrapper.json
