Personally WSL has always been riddled with issues for me. I mainly used it for dev things before I switched to linux entirely. Recently I came back to Windows to try some of AMDs new graphics driver features and decided to try out WSL 2. Hell, Windows fucks up so much basic shit in there, i couldnt even run 'git init' because some permission issue with drive mounting. Had to move my entire project to a separate drive just to make it work. The way Windows handles the filsystem, permissions and "cross-OS" functionality is so weird and always results in some issue, making the Linux experience feel significantly more wonky than it needs to be. Performance is also a pain, since i had to love my project to a disk that was not part of WSL reading and writing files in VS Code becomes significantly slower.
I have a pretty high end rig and even my PC runs slow when using WSL, its great to have an option for linux in windows but when a docker container or even just a VirtualBox machine performs better than WSL i have no fucking clue why youd use it.
Thanks for listening to my rant. Take it with a grain of salt ig, maybe im just incompetent and doing something very wrong.
You can check ProtonDB for specificerar games compatability. Most games from steam just install and run as usual. But other launchers and some games with anti-cheat can be a bit more wonky to get running or just dont work at all.
