If it works and the user is happy, why not Judy go with it? Surely with a ton or research you can find why it works better on cachy and with much not time you can try to replicate on a different distro the myriad of things that can be, and then spend time making sure nothing breaks.

Or, hear me out, you can just play the game you wanted to play on the fist place.

I'm using Bazzite because it's the first distro where gaming wise everything just works. Only had to fight with the printer/scanner. I wanted to use other OS, but seriously, I also want to play and use my time doing something other than solving problems I've created.

If catchy is a batteries included distro that people can use, even if their performance gains are questionable, let them. There's no shame on that.
