I think it’s not the moment for Linux gaming in general, but more so the moment for certain devices like the Steam Deck. Fixed hardware platform is what you need to precompile shaders and eliminate stutter. I would love for Valve to put out a box that sits under your TV with an APU on par with the PS5
Mesa (the Linux OpenGL driver) supports caching shaders on any GPU. And Vulkan essentially has shader caching built in at the specification level. I know that Steam ships precompiled Vulkan shaders, and while there's no equivalent for Mesa's shader cache yet, it shouldn't be a huge issue since it would only cause a short delay the first time the shader is loaded.
