lutris missing vulkan libraries?

So.. I finally somehow managed to install crystal.

When I installed and opened Lutris. a message showed up that some vulkan libraries are missing.

but for some reason I couldnt install it. The packages were not available in the repos.

Hello, welcome to Crystal! 🙂

Those packages are available in the multilib repo which is not enabled by default.
Have you correctly enabled it according to the instructions for Arch and derivatives: https://github.com/lutris/docs/blob/master/InstallingDrivers.md#arch--manjaro--other-arch-linux-derivatives ?

i did a mistake,

thank you very much, you helped me.
