Programmer and big Linux fan here. I use Linux for multiple servers/vm's. For a while I also had Linux on my desktop and using a Windows VM with PCI-passtrough for gaming. It works. However I came to the conclusion I was only using the PC for gaming (on the VM), and doing all my programming on my MacBook. So basically the Linux part on my desktop was just useless. Although I want to, I don't have any use cases for Linux on the desktop.
Edit: I do have a steamdeck. Love the thing!
