Some games, others run worse. It’s usually within 10% either way, which isn’t something I’d personally pick an OS over. You can probably tune things to eek out an extra percent or two, but imo that’s not worth it unless you’re really into that kind of thing.
theres no “ready out of the box” in these lands
That’s just not true. Most of the time, Linux works great out of the box, but there are some common areas where that’s not the case:
laptops with dGPUs - Linux just doesn’t handle graphics switching as well as Windows, but the solution is easy as OP found out
crappy WiFi cards - just buy Intel NICs
crappy sound cards - less of a problem these days, but sound can still be a massive pain
And that’s pretty much it. If you buy quality hardware, your OOTB experience is probably going to be great! If you buy an AMD GPU, it’ll be even better since you don’t even need to install graphics drivers! I had zero issues on my desktop switching between distros (everything just works), and my only issue with my laptop was using very recent hardware, which was fixed with kernel updates (there was a known bug with sound over HDMI on my AMD laptop).
Imo, Linux is much more likely to “just work” than Windows, assuming you’re installing the OS yourself. Every time I’ve installed Windows, I’ve had to track down a bunch of drivers, downloading Wi-Fi drivers on my Linux computer and installing them with a USB stick. That sucks.
