I started using Proton recently and it is quite impressive. Some games have native support, some use Vulkan, others want to run on SteamDeck. I haven't booted Win 11 in more than a month. Not having to dual boot any time I want to switch work/fun is great - even if reboot doesn't take that long these days. I tend to play older, single player games, not everything is perfect, but I like it much more than being frustrated by Windows - using Fedora btw.
