OK, now lets go through some of this information…
While you do have a decent amount of RAM, its probably still a good idea to set up some SWAP.
If you do not want to create a partition, and indeed I find zram in particular more performant, you may opt for a swap-file or zram. Some guides are here:

Looks fine.
Also looks fine.
But ok … we have 2 GPUs … one amd and one nvidia.
It looks like the amdgpu is being used by default.
Now I will ask for some other info;
mhwd -li -d
and some tests;
glxinfo | grep 'renderer string'
DRI_PRIME=1 glxinfo | grep 'renderer string'
prime-run glxinfo | grep 'renderer string'
Note: If you do not have the glxinfo command it is provided by the package mesa-utils.
PS
This isnt really OS-dependent or necessarily of high importance, but I do notice you have BIOS updates available. Indeed in your case some of those updates are marked for security and performance.
