I haven’t used it, but https://nobaraproject.org/ aims to be a great gaming distro. I personally use EndeavourOS (Arch based) and have found being an up to date rolling release to be pretty useful and I’ve seen games run better over months of updates. For example Cyberpunk 2077 ran terribly when other titles ran well. But there’s been updates recently and now it’s doubled the frame rate to a playable level.
