In my experience, gaming distros primary benefit is being preconfigured with apps and patches you’d install on a normal distro.

For normal distros, this difference isn’t big enough to impact your distro choice in most cases. The reason these get recommended is due to their post-install setup being easier than the distro its based on, hence being friendlier to new Linux users.

However, for immutable distros this is a big factor as it reduces the need for layering. Layering makes updating much slower, so less is always better.

My journey went Ubuntu (2012) -> Kubuntu (2018) -> Manjaro (2020) -> Fedora KDE (2022)

Most computers I had were used and low-end so Linux was always my preferred OS, but I always dualbooted with the version of Windows or MacOS the machine came with when I could.

My current computers have been Linux only for a couple years now, thanks to Windows being a headache and MacOS being inflexible.

It says in the article that triple buffering only activates if your GPU struggles to render the desktop. That means old and weak iGPUs are getting this. For your desktop card nothing should change.
