Some games have a complicated enough Anti-Cheat that it’d be an absolute pain to get it working with Linux. Honestly, it’s not worth it to gain 3% more players. I’d recommend just running a Windows VM in Linux.

Running a VM would imply dealing with VFIO. For a recently converted casual Linux gamer it’s better for them to dual boot than deal with that headache.

I get your point in dual boot being less of a headache, but learning some libvirt/qemu and running your own virtual machines is a lot of fun.
I went for a virtual Fedora Workstation with VFIO and a dummy plug. Then I use Sunshine/Moonlight to stream my gaming session to whichever device I feel like using.

Anytime I wanna try something I feel might crash my Fedora I simply backup the virtual machine files and go to town on it.
If I fail I roll back and try again.
I run my servers the same way, as virtual machines that I can easily backup and experiment with, and I do think it makes learning a lot quicker.
