Remember the days when everyone and their pet iguana was raving about Arch Linux? You couldn't escape the ever-so-subtle "I use Arch BTW" remarks in every Linux forum. Well, move over, Arch, because NixOS is here to steal your thunder! Nowadays, it seems that you can't browse YouTube or read a blog without stumbling upon someone extolling the virtues of NixOS and how it is the epitome of computing perfection. But hey, who needs critical analysis when we can jump on the hype train and declare NixOS as the new Arch? Because that's exactly what's going on. NixOS has now become the self-proclaimed prodigy that's poised to dethrone Arch Linux as the holy grail of Linux distributions. The time is calling, my friends! It's time for you – the seasoned Linux enthusiast – to dust off your keyboard warrior capes and embark on a new crusade. So, grab your Tux plushie (or, your pitchforks if you belong to the world of devils) and let's embark on an adventure through the enigmatic world of NixOS (and let the memes commence)!
That is incorrect to my knowledge. Back when I used Arch, you still needed to enable multilib which I don’t think has changed. You need a wiki entry to tell you how to do that.
AFAIK you also need to manually install yourself a Vulkan driver. I’ve recently helped a person who had opted for AMDVLK here and it broke in one game but was working fine in others.
That sort of thing doesn’t really happen with NixOS because enabling desktop support implies the presence of a Vulkan driver and we provide a sane one by default (currently RADV via mesa or nvidia when you enable proprietary drivers).
