There's so many games on Steam that run native on Steam or really well via Proton. I abandoned Windows a few years ago with video games being my last hold-out. If it doesn't work under Proton or isn't native, the game is a hard pass for me.
To each his own. Windows isn't that awful these days and wrestling with Nvidia drivers on Linux is a PITA and entirely Nvidia's fault.
Their drivers on Windows aren't that great, either.
I boot Win10 for Steam games, Fusion360 and AutoCAD.
