Ah I see. I guess it makes sense to squeeze out every single % in such cases.

also I had to set my CPU governor to performance

I believe most DE has an addon or equivalent for setting that.

How much of the tweaking is actually noticeable? Not trying to be a dick here. I'm so old that we didn't use to have GPUs, we had graphics cards and nobody had a "rig". Overclocking or hardware mods was the only way if you weren't willing to spend money on new hardware. Not saying Bazzite is that kind of distro but I'm so old I don't trust some spazzed out maintainer with cat ears and a discord channel. Let me break my own shit, you don't have to do it for me.

I have the exact same experience as you with Debian 11-13 and gaming. Both with Nvidia and AMD cards, various chipsets etc. Everything works. Sometimes after reading a few lines of official documentation and installing a package or two but that's about it.

The only thing that ever required some head scratching was the infamous EA and Rockstar launcher but that's not a Debian or even a Linux problem.... Everything else is identical to windows. Click install. Wait. Click play. Everything works in-game. What am I missing?
