I would just use my desktop for that use case. There's still a small minority of games that just don't work via proton but it's really a minority.
I've also seen a handful of games with linux builds that just don't run properly because they update the game but don't do enough QA to the linux build or simply don't put resources towards linux issues to the same degree that windows gets.
I swear to christ these people are the dumbest motherfuckers, and nearly half the country is on their side.
The fact that so many idiots are falling in line with ignorant bullshit is just proof of how political advertising is insanely effective. The stance against vaccines is not a medical one - there is really zero debate there - it's a political one based on feelings, surely a great way to handle medical conditions if you're stupid, ignorant and incapable of even the most basic of critical thinking.
