I just did a fresh Arch install last week. Running 6.4.1 kernel on a ThreadRipper CPU with an RTX 2070 Super and an RTX 3060. Driver version 535.54.03 and CUDA 12.2. Everything "just works". There was no manual configuration, tweaking or hacking around needed. No issues running Wayland, Proton is handling gaming beautifully and not a sign of screen tearing.
The experience is different for everyone it seems.
I can play almost all single player games, whether they officially support proton or not; the only major game I have been unable to play (despite following all instructions online) is Gris.
