For example, to install Steam I would run sudo pacman -Syu steam. On a typical Arch setup that’s all that’s needed.
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).
