I don’t use a game optimised version of arch, I also use NVIDIA hardware, and I have no problems. I run a single monitor and have no need for Wayland at this point in time. X11 just works.
However, I game on desktops. My laptop is for work and that runs an Intel iGPU. It also runs Linux, without problems.
May I recommend KDE Neon. Canonical have ruined vanilla Ubuntu with their Snaps agenda.
Microsoft have Microsoft accounts, Canonical have Snaps…
