I've got a Steam Deck which is essentially a portable Linux machine, and I've been positively surprised by how well every game I throw at it has worked (even the ones that aren't officially verified to work on the Deck). Of course it's an underpowered system compared to desktops, but Proton - the not-emulation system based on Wine - is absolutely terrific, and it can be used on other Linux OSs than just SteamOS. I'd recommend giving Linux a go on a separate partition, you might find that your games run pretty much out of the box as long as you have Proton installed
