its nowhere near consoomer friendly yet on linux
it works but has issues; overlays basically all don't work so you're stuck with a scuffed vanilla experience
either some recent beta update or nvidia driver update absolutely killed steamvr on my install and I haven't revisited it in about a week

overhead in linux is usually less if you're on a light DE but if you're running games through proton you'll oftentimes have extra overhead just due to translating the DX calls to Vulkan and loading up shaders as you need them
normal pc games are far more usable via proton than steamvr ones will be at least for now
