Seem to be missing 64bit radeon driver for vulkan (steam Pharoah Dynasties running in LLVMpipe)

Hi there,

i have a late 2025 era tumbleweed kde install on a HP omnibook 7 13 (ai 350 apu), updated to the latest 0706 release today.
Never been able to run the total war games, always crash on campaign load.

Getting 1fps on the Total War: Pharaoh Dynasties campaign benchmark, and using:
vulkaninfo --summary

indicated that the vulkan driver being used for this game is llvmpipe.

so, i tried forcing steam to launch the game with the amd vulkan driver with this command:
VK_DRIVER_FILES=/usr/share/vulkan/icd.d/radeon_icd.x86_64.json %command%

Only to find i don’t have a “radeon_icd.x86_64.json” file in that folder.
Instead, the only readeon driver file is “radeon_icd.i686.json”.

Anyone know how I got to this pickle, and what might be the best way to rectify it?

Thank you.

For that libvulkan_radeon needs to be installed.
