I didn't have to spend hours getting my GPU to work on Linux... What were you using exactly, as a distro and as a GPU? Not that I try to invalidate your experience, but afaik, if you have a AMD or Intel GPU, it should work out of the box and if you have an Nvidia GPU, any user friendly Linux distro that is optionally made for gaming have drivers preinstalled and can easily be updated through a GUI or a two words command so that you can directly play as soon as you installed the distro.
