Does someone has issues with Steam Proton?

Q&A
1

Hi, currently I’m love with the performance that my PC is getting with this distro.
I’ve installed Steam to try proton on World of Warships but it isn’t loading.
vulkaninfo says this on top:
ERROR: [Loader Message] Code 0 : /usr/lib32/libvulkan_intel.so: wrong ELF class: ELFCLASS32
ERROR: [Loader Message] Code 0 : /usr/lib32/libvulkan_radeon.so: wrong ELF class: ELFCLASS32
My Setup:

Not all windows games that use Proton will run - The success rate in my personal steam library is maybe 50%. Many games just won’t work due to missing API functions in Proton or the underlying wine that Steam uses. This isn’t a distro specific problem - everone uses mostly the latest wine versions.

Steam uses it’s own version of wine / proton and we can not change that. This is especially the case if you have installed steam through flatpak.

Hi, thanks for replying!
Well, I test this game on openSUSE Tumbleweed and Linux Mint and I’m not having issues. I was reading something about vulkan and maybe there are some missing files.
Dota 2 with vulkan works btw
I installed Steam using its tarball

The Steam Linux Runtime container tool is not installed.

That still means you’re using Steam’s version of wine/Proton, which isn’t something we can change/fix.

These errors can likely be safely ignored. It’s just an indication of 32-bit and 64-bit drivers: BLOCKER: Wrong ELF class (Gentoo, Argent, Debian, Arch) · Issue #108 · KhronosGroup/Vulkan-Loader · GitHub
