Due to intel_pstate poor performances as of late, I have decided to disable it by default. It is still builtin though, and you can add intel_pstate=enable or intel_pstate=passive to your kernel command line (in GRUB for example) to either use plain intel_pstate governors or make use of acpi_cpufreq governors while keeping full support for turbo frequencies, respectively.

A custom Linux kernel 5.5.y with specific PDS, MuQSS and BMQ CPU schedulers related patchsets selector (stock CFS is also an option) and added tweaks for a nice interactivity/performance balance, aiming for the best gaming experience.

Various personalization options available and userpatches support (put your own patches in the same dir as the PKGBUILD, with the ".mypatch" extension.

MuQSS : http://ck-hack.blogspot.com/

BMQ : http://cchalpha.blogspot.com/

As of BMQ 5.5r1, timeslice can be adjusted through kernel boot parameter bmq.timeslice= (value should be >=1000, default is 4000)

PDS-mq was originally created by Alfred Chen : http://cchalpha.blogspot.com/ While he dropped it with kernel 5.1 in favor of its BMQ evolution/rework, my pretty bad gaming experiences with BMQ up to this point convinced me to keep PDS afloat for as long as it'll make sense/I'll be able to.

You can find prebuilts on chaotic-aur, but if you need the extra-spice of per-arch optimized prebuilts, you can find PDS and MuQSS variants daily builds here : https://repo.kitsuna.net/ - Thanks to LordKitsuna.

Comes with a slightly modified Arch config asking for a few core personalization settings at compilation time. If you want to streamline your kernel config for lower footprint and faster compilations : https://wiki.archlinux.org/index.php/Modprobed-db You can enable support for it at the beginning of the PKGBUILD file. Make sure to read everything you need to know about it.
