Isn’t a normal VM with GPU passthrough that? I’m genuinely asking, because I’ve asked my original comment’s question several times before and never received answers except something about wanting to buy a computer with the OS installed from a brick-and-mortar retail store, which didn’t seem to apply to you given you’ve already installed GNU/Linux.

I said personally because I personally have felt less addicted to games as I personally have grown older. Of course most people are different from me in many ways, but I don’t think everyone is in every one.
Hardware passthrough does exist and I only expect it to improve, but we're still a ways from reaching "just works" level.
I'd legit rather kill myself than use Windows as my primary OS, so I dual-boot, but I'm frankly interested in that too. Not for games though, but for real-time audio. Does anyone have any experience with running a DAW on a Windows VM? Is it worth the effort?
Of course it helps that RDP and freeRDP both work very well. Whenever I need Windows I just fired up and I'm there instantly. If I want to play a game I go over to my gaming machine. Personally I never mix games and business.
I assume IOMMU passthrough works pretty well, when available. Also, I’ve been pleasantly surprised by how well Steam’s proton works even with applications that aren’t officially supported.
