I want to try ESO for you but 125GB download...
Guild Wars 2 work fine for me especially after they migrated to Chromium many months ago. I even use ArcDPS + Reshade with no problem.
Maybe you can try Krita for photo editing and Kdenlive for video editing.
I'm on Manjaro Plasma Desktop. Select use Proprietary driver when booting so it will use/install official Nvidia driver out of the box.
