Just watch the LTT videos about gaming on Linux. Linux is a Cluster** of an OS to troubleshoot and configure.
I'm a dev myself I love my Arch and everything but this OS is NOT meant for normal people.
Its 2022, people don't want to fiddle around with a terminal.
Until Linux and its users don't fix the core problem of linux and thats usability, I don't see people switching to it.
Maybe steam changes this.. but we will see..
