As someone who is looking to go Linux, do most windows apps work now through Wine or VirtualBox ? I know Valve did a lot of work for games.
It’s been 4 years since I even took a good look at it.
Just anecdata, but the few things I use via Wine have all worked fine. I use yabridge so I can use windows VSTs in my Linux DAW.
Games (if they don't use kernel level anti cheat systems) are all flawless with Proton.
But, I honestly don't have a need to use much other windows only software. Almost everything I need to use has Linux versions, or alternatives that fit my needs.
Most things work great. There are some niche things that do not work so well. Example: SteamVR,Vive VR Hub, some AntiCheat for games.
A lot of them do, but for almost everything there are native alternatives.
I haven't used Wine directly in years, only indirectly through Steam.
