AMD Vulkan Standalone VS AMD Vulkan Pro Why Such Performance Difference?

[Echoa]

@niereklamuj

OK then.
So what do you suggest for better performance to be at par or better than amdgpu-pro?

I’m little confused. From your last post, it seems to me that you are mentioning 3 drivers:

andgpu-pro
mesa
amdvlk

I’m confused. I’ve read so much about it, but still cannot grasp what is going on.

Which packages should I install to have the best performance in CS:GO in Vulkan?

Also, if I uninstall andgpu-pro I won’t have AMF support for recording in OBS, what should I use alternatively then?

AMD has 3 linux drivers

Closed Source AMGPU-pro
Opensource driver made by AMD AMDVlk
Opensource driver made by OSS devs Mesa/RADV

Mesa comes installed on default and thats what you want, but to make sure you have all the bits

sudo pacman -S --needed lib32-mesa vulkan-radeon lib32-vulkan-radeon vulkan-icd-loader lib32-vulkan-icd-loader

to keep AMDGPU-pro for AMF but use RADV for games and such you can add this to your /etc/environment file

VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/radeon_icd.i686.json:/usr/share/vulkan/icd.d/radeon_icd.x86_64.json

and in the com.obsproject.Studio.desktop change the Exec= line to
Exec=env VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/amd_pro_icd32.json:/usr/share/vulkan/icd.d/amd_pro_icd64.json obs

make sure to uninstall AMDVlk and youll have AMF for OBS/Encoding and RADV/Mesa for rendering/games/etc.
