Spotted a Reddit post about Zena OS…
I’m going to check it out… I guess I should link here from that other topic that seems to be mostly discussing gaming on Linux…
Anyway - downloading the “non-NVidia” ISO now and going to try it out in QEMU/KVM…
Interesting - they seem to take the same approach as Pop!_OS - i.e. a build for everything else, and a build for NVidia GPU systems…
You can game on it according to their page - with simple “gaming install” command 
I won’t run this as my main - I’ll stick with a more multi-purpose distro like Ubuntu… I need various things - e.g. I need CITRIX to work on my main desktop for my job… Yeah - Citrix should work everywhere (I’ve used it before on armhf running Debian Jessie) - but I’m not gonna risk it
