I think a lot of cachy performance is placebo, because Steam games use the container runtime's Debian 11 libraries, it doesn't use the native CachyOS ones at all.
I'm CPU-bound on one of the games I play, and cachy's scheduler may have made a difference for me. I was also fully on the closed-source NVIDIA drivers in Fedora, and had been totally out of the loop that that the kernel driver had been open sourced. And, cachy had me on a more recent version of the driver.
None of these things are truly unique to CachyOS, but nonetheless I do think I experienced a boost when I switched.
