Did you try Desktop Mode on the Deck? Makes things a lot easier. Haven’t had much issue with things like this with my Steam Deck, but on Linux PC, I’ve had none. Ever. Try Bazzite, it’s built for gaming.
I would just Google, “using bottles/lutris to install game on Linux” and I imagine you could find people walking through it.
Not sure what quick settings you mean, but have you tried Bazzite yet? I’ve been using it on my laptop for several months now, and it’s been fantastic.
