I had a lot of the same issues you are stating until I switched over to fedora. I have an nvidia Optimus laptop and it was quite the pain until I installed fedora and used the proprietary drivers from rpm fusion. I use b9ttles and steam to run my games and I can play most of the games I want to. Even Wayland works nice. I am using the Plasma spin of Fedora 40. Hope you can find the solutions to your problems.
Protip, use Rufus to create the windows install stuck and disable all the telemetry if you want to.
