Clip Studio Paint doesn't work on Linux, and neither does Paint Tool Sai (which are the only art programs I'm extremely familiar with) and a lot of game developers with kernel anti-cheats do not want to develop for Linux due to the lack of a fully secure environment in the OS. In fact, someone could actually make a Linux distro with its only focus being cheating. However, if Valve manages to create an actual secure enviroment in SteamOS (and I do trust them to find a way) and exports said environment to other Linux distros, we may actually see games like Battlefield 6, Valorant, GTA V, and Call of Duty on Linux.
If that ever happened I would never, ever use Windows again.
