Hello.
I booted up Skyrim after doing a fresh install of KDE Dragonized Gaming Edition and I noticed that I'm only getting around half the performance that I would get on Windows 10. My output from inxi -Faz is;

Some things I have already tried is to install the NVIDIA drivers as it says in the Arch Wiki, by using
sudo pacman -S nvidia
https://wiki.archlinux.org/title/NVIDIA#Installation
Is there anything else I can do? I was able to get up to 60 FPS when I was using Pop!_OS so I know it is possible to get better performance, however I admit I'm still fairly inexperienced with Linux so I'm not sure what is left to be done.
