Yes I am aware. Even before Proton I was one of those geeks with one Radeon for a Windows VM and one cheap GPU for the host system.

But it's just too much hassle. I'd rather just boot up my big Windows gaming rig. I view it as a modular Xbox that I build myself.

So no matter how far we come in Linux, most people will still have a "Wintendo" PC console for gaming.
