This isn't a guide, just something i think may help. To install Steam on an Arch-based distro in most of the cases a simple sudo pacman -S steam will do just fine.

The installation will ask you to select a valid vulkan package from a list. And in most of the cases that's just fine... most of them.

Then you have your very "picky" old nvidia GPU which works only with a specific old nvidia driver and if you try to install anything else, there will be a conflict. Now you can try to remove the old (working) drivers and try your luck. But looking online i find a simple way to skip this passage and install Steam.

sudo pacman -S steam --assume-installed lib32-vulkan-driver

I just use TKG's installer, it's pretty much fixed all of my NVIDIA-related problems:

git clone https://github.com/Frogging-Family/nvidia-all
cd nvidia-all
makepkg -si

The default is vulkan-beta drivers via DKMS. You may need to manually install linux-headers but you may already have it installed from other DKMS-related activities.
