alt Hacker NewsI'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.
To expand a little bit, I think it might clearer to say that CachyOS does out of the box what many other distros could also do with manual configuration. So, in that sense (default) CachyOS probably is faster than (default) [mainstream distro].
