Just saying, if you have the HDD space, I'd say give dual booting a shot. you'll probably be surprised how usable Linux is for gaming these days.
There's a tiny gap in the early windows 9x days that I've been thinking of filling by upgrading my Dosbox Win 3.11 to Win 98. Overall though, it runs a greater percentage of dos/windows games than any dos/windows machine I've ever had access to.
(I'm considering moving to FreeBSD though. Dosbox runs fine, and Steam + Proton sort of works there, apparently. Checking it out in more depth soon.)
Now? I haven't even thought about compatibility in months. I don't even look at the user tweaks anymore, when it used to be a constant factor. Granted, I don't play multiplayer games with anticheat, which last I heard was still a lingering issue. Your mileage may vary, but I completely removed my Windows partition a while ago, and haven't even thought about since.
I'll be the first to say it's not perfect, but it's 100x better than it was 5 years ago. I'd say at least 70% of steam games just work when you hit play, 25% require a bit of configuring to get working, and only around 5% refuse to work at all.
I haven’t gotten a machine with a proper graphics card in years and I wanted one to experiment with LLMs locally, so I got a gaming PC setup.
