I currently run windows 10 on my main desktop PC, and also have a steam deck that I sometimes use in desktop mode instead of my desktop. With the way Windows is going, and the way Linux Gaming is dramatically improving, I might consider ditching Windows, at least for the most part, on my next PC build. What would be the best distro to use for gaming, with casual use as well? Any suggestions?
Most regular distros are good enough for gaming. The only issue you’re likely to run into is with graphics drivers (I recommend going for AMD graphics on that build), and the availability of certain software in certain formats (gaming software is more likely to be available for Debian or Ubuntu based distros).
If you like the Steam Deck’s desktop mode, you might enjoy another distro with the same desktop environment (KDE Plasma). I’m partial to KDE Neon, a snappy Ubuntu LTS spin with all of the latest KDE software.
