I'm lucky that I don't need long battery life, I'm always plugged in for gaming, so I have set the Nvidia GPU in Dedicated mode. I suspect not having both (optimus or prime) have eliminated a lot of issues, it works well with Wayland and Plasma and games like BG3 and Guildwars2 under Proton+Xwayland.
Actually it's not too bad on the battery when not gaming, despite always running NVidia.
