I’ve been running Garuda with KDE (dr4g0nized gaming spin) for over a year and have had a great experience. Arch gets a bad rep for breaking updates, but I’ve never experienced any. My Steam Link in the living room has mostly functioned fine, but it has been a bit finicky lately. As for the AUR, I think I have maybe a dozen packages from there in my machine, partially because Garuda ships with Chaotic-AUR, which has a more robust (read: existant) review process for submissions. I have used both Nvidia and AMD GPUs and both have worked flawlessly. I don’t game as much as I used to, but I’ve been nothing but happy with my Arch gaming experience.
