How does gaming on Gentoo compare to other distros in terms of performance

I’ve tried to look for benchmarks and comparisons and can’t seem to find any for Gentoo. I’m looking to switch to Gentoo from Arch and I have the latest and greatest hardware with a Nvidia GPU.

I’m also a 4k gamer. 3-6 FPS can be the difference between a smooth experience and screen tearing. I am willing to put in the time and effort of learning Gentoo and switching distros if there is a performance gain in gaming. I run native games and steam+proton.

No, I don’t plan to do anything else with my desktop other then browse the web.
