It doesn't come with any gaming apps (but can be installed manually or use their package that installs all the essentials). they also have a proton/wine fork and has patches related to gaming no issues there, and later after some updates(idk how it gets it) you will get LFX (Latencyflex) you can enable it with LFX=1 In environment variables in games and there was no issues at all in gaming (Note you can view cachyos as more of a performance distro rather then a gaming one) .

In my experience, Nobara requires way less fiddling and works out of the box. CachyOS was way more fiddly. I have newer hardware so things are a bit weird for me in general.

Do wish Nobara had more maintainers. Cachyos isn't a whole lot better in this regard either, if you wanted something for gaming that has a lot of maintainers you should probably go for Bazzite. Personally, I had issues with Bazzite as well, Nobara seems to play nicest with new hardware out of the box.

If you are on another arch based distro you can also add their repos: https://wiki.cachyos.org/features/optimized_repos/
