# urpmf nvidia_icd.json|sort -u
x11-driver-video-nvidia390:/etc/vulkan/icd.d/nvidia_icd.json
x11-driver-video-nvidia-current:/etc/vulkan/icd.d/nvidia_icd.json

As those are the only packages that supply the file, an enhancement bug report
to have them set the VK_ICD_FILENAMES variable would be appropriate. As the
program Warthunder is not a Mageia package, all we can test for is that the
variable is set, not whether or not it fixes that program.

For testing, we can ask that user on forum if he wants to try.
I link in that thread to this bug.

Comment 1 Thomas Backlund 2021-10-18 23:23:12 CEST 
setting VK_ICD_FILENAMES by default to the nVidia icd would force it on every user with nVidia packages installed, even if they might want to use the mesa ones...

Something seem to have changed, as when user reverted updates, it worked.

So we have a system change of policy/preference?

How do users normally choose, and how will they know they have a choice?

Regardless of solution here, it feels like these things should get noted in our wiki, like here: https://wiki.mageia.org/en/Setup_the_graphical_server

Also, I believe that page should get updated and revised by someone who knows these things well. (not me) ...

I added section

@tmb, Feel free to close this bug if you agree.

Comment 4 Giuseppe Ghibò 2021-10-19 22:19:07 CEST 
What is strange is all this subject is that according to what reported in the forum, under mesa 21.1 everything was working without setting any env var, so I wonder whether in passing from mesa 21.1 to mesa 21.2 some hardcoded path for ICD files has been changed or get lost. Second, apart the game Warthunder, does this happens on any game using Vulkan?

mga8 is EOL, advancing MGA8TOO to MGA9TOO
