I don’t know of anything like what you’re looking for, but I have been using CachyOS for over a year now and I really like it. If you’re looking to get the most performance out of your machine for gaming I wouldn’t think you’d want such a stable release like Debian anyway.
Edit: like the other poster mentioned, I never did any testing or anything, but I also didn’t notice any major improvements when I switched from vanilla Arch to CachyOS to be fair.
Really shooting from the hip on this one, huh?
