lib32 Vulkan libs needed for Proton to work

When i first tested Steam Play / Proton, every game crashed immediately.
After a while i found out that it works when i install lib32-vulkan-icd-loader and lib32-amdvlk. But since i am using Steam runtime instead of native runtime, i was wondering
if this is expected behaviour. I thought Steam would ship all relevant libraries then. It's also not mentioned in the ArchWiki (https://wiki.archlinux.org/index.php/St … Steam-Play)
Are those libraries just an exception and it should be added to the wiki or is there something wrong with my setup?

Maybe related: I tried to add Heroes of the Storm as external game and the launcher only works if the wine package is installed.
The game doesn't start either way, but that's probably a different story…

Well yes you need "some" vulkan lib provider for 32bit just like you need some 32bit lib for opengl. Those are hardware compat libs they aren't going to come from the Steam runtime.

yeah i ran into this issue with lutris as well. at least lutris gives you a warning you're missing lib32 vulkan files. in my case since i have a 2070 super, i just needed lib32-vulkan-icd-loader. i do think the steam wiki should be updated to include tips about libraries you need. especially considering vulkan and dxvk are pretty much standard now for gaming.
