I don't run GL games anymore on elf/linux. And it has been a while. Most cross-platform game engines have a vulkan backend now.
Very small teams are able to show games running the latest UE5.x engine on native elf/linux, vulkan ("vein", "shmaragon" something).
But the steam client... is still 32bits and x11/GL hard dependent...
I still plan to code my own wayland compositor once the steam client is ELF64 and does proper wayland->x11/vulkan->CPU fallbacks. It will feel weird to have a clean 64bits system.
