For gaming? You need a distro that does stuff for you!
To elaborate, if you’re using wine bottles, you’ve gone waaay into the land of manual from-scratch configuration, when you should just use stuff from a community that spends thousands of man hours figuring it out and packaging it.
Try CachyOS or Bazzite! They have a bunch of packages like advanced versions of preconfigured Proton one install away.
For docker… yeah, it’s a crazy learning curve if you just want to try one small thing. It’s honestly annoying to go through all the setup and download like 100 gigabytes of files just to run a python script or whatever.
You can often set up the environment yourself without docker, though.
And to reiterate, I’m very much against the ethos of “you should learn how to do everything yourself!” I get the sentiment, but honestly, this results in suboptimal configurations for most people vs simply using the packages others have spent thousands of hours refining.
