To change bootsplash install a bootsplash package and modify the following files accordingly. (example is for manjaro-glitch)
/etc/mkinitcpio.conf
HOOKS="... bootsplash-manjaro-glitch"
Append the following to GRUB_CMDLINE_LINUX_DEFAULT:
/etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="... bootsplash.bootfile=bootsplash-themes/manjaro-glitch/bootsplash"
Update initramfs and grub:
sudo mkinitcpio -P
sudo update-grub
Install fancontrol-gui package, changes will be saved in configuration file.
sudo pacman -S fancontrol-gui
Enable fancontrol:
sudo systemctl enable fancontrol.service
This is my custom config file where most fans are controlled by GPU temp (do not use, just for reference):
/etc/fancontrol

Create a modprobe config file and set the dependencies of the modules manually. This is a pain to find out but was unfortunately necessary so my sensors always have the same ids :(
Note: This example is for nct6687 temp. sensor (I have that one on my MSI B550 Tomahawk), you have to substitute for yours)
/etc/modprobe.d/fancontrol.conf
softdep nct6687 pre: zenpower
softdep ucsi_ccg pre: nct6687
softdep hid_logitech_hidpp pre: nct6687
During shutdown my fans went bonkers, so I added a script that is called when fancontrol service is stopped.
Create a stop script (modify for your hardware):
/usr/sbin/fancontrol-stop.sh
#!/bin/sh
echo 60 > /sys/class/hwmon/hwmon4/pwm1
echo 60 > /sys/class/hwmon/hwmon4/pwm2
echo 60 > /sys/class/hwmon/hwmon4/pwm3
echo 60 > /sys/class/hwmon/hwmon4/pwm4
echo 60 > /sys/class/hwmon/hwmon4/pwm5
echo 60 > /sys/class/hwmon/hwmon4/pwm6
echo 60 > /sys/class/hwmon/hwmon4/pwm7
Make script executable:
sudo chmod +x /usr/sbin/fancontrol-stop.sh
Add the stop script to fancontrol service config:
/etc/systemd/system/multi-user.target.wants/fancontrol.service
ExecStopPost=/usr/sbin/fancontrol-stop.sh
NOTE: Many examples are only for amdgpu driver and for 144Hz display.
Create X11 configuration file:
/etc/X11/xorg.conf.d/20-amdgpu.conf
Section "Device"
Identifier "AMD"
Driver "amdgpu"
Option "VariableRefresh" "true"
Option "TearFree" "true"
EndSection
Add this to sddm startup script (modify for your refresh rate):
/usr/share/sddm/scripts/Xsetup
xrandr --rate 144
Add both options to the [Compositing] section of kwin config (adapt for your refresh rate):
~/.config/kwinrc
MaxFPS=144
RefreshRate=144
Install wxedid package.
Find currently used EDID:
find /sys/devices/pci*/ -name edid
Copy to a new file (change to the path of the original edid you found):
cat path-to-edid > /usr/lib/firmware/edid/modified-edid.bin
Then edit with wxedid, change MRL Vfreq and save.
Add amdgpu driver together with edid file to initramfs so it's loaded during init:
/etc/mkinitcpio.conf
#MODULES=""
MODULES=(amdgpu)
#FILES=""
FILES=(/usr/lib/firmware/edid/modified-edid.bin)
Generate new initramfs:
sudo mkinitcpio -P
Append the following to GRUB_CMDLINE_LINUX_DEFAULT:
/etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="... drm.edid_firmware=DP-1:edid/modified-edid.bin"
Update grub:
sudo update-grub
Uncomment the following in configuration:
/etc/pulse/daemon.conf
high-priority = yes
nice-level = -11
realtime-scheduling = yes
realtime-priority = 5
...
resample-method = speex-float-10
Disclaimer: Be very careful with overclocking/undervolting, my settings are chosen for my chip after a lot of trial and error and greatly vary for each chip.
Append the following to GRUB_CMDLINE_LINUX_DEFAULT:
/etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="... amdgpu.ppfeaturemask=0xffffffff"
Update grub:
sudo update-grub
Execute sudo pacman -S upliftpowerplay to install upp command from AUR for modyfing radeon soft power-play-tables.
Create a script for undervolting that you can execute when you need it.

If you run into this issue you need to build a patched kernel - see this issue.
Best way to do this under arch is to first clone the kernel you want to use, e.g.: git clone https://gitlab.manjaro.org/packages/core/linux61.
Then build the kernel with makepkg -s -f (this fetches kernel source and applies distro-specific changes).
When you finished building, modify the kernel source under src/linux61.
(The file to patch there is drivers/gpu/drm/amd/pm/amdgpu_dpm.c).
Then build again with makepkg -s -f -e so only your changes are rebuilt.
Lastly, install your custom kernel with e.g.:
sudo pacman -U linux61-6.1.0-1-x86_64.pkg.tar.zst linux61-headers-6.1.0-1-x86_64.pkg.tar.zst
sudo pacman -S zenpower3-dkms
Blacklist k10temp driver:
/etc/modprobe.d/k10temp-blacklist.conf
blacklist k10temp
amd-pstate driver is compiled into the kernel since kernel >= 6.1.
To enable it append the following to GRUB_CMDLINE_LINUX_DEFAULT:
/etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="... amd_pstate=passive"
Then update grub:
sudo update-grub
After rebooting verify that amd-pstate is active:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver
Switch to the performance scheduler (you might want to add this to your overclocking/undervolting script):
sudo cpupower frequency-set -g performance
Install mangohud package.
Then enable mangohud in lutris settings - either per game or per runner (systemwide).
Modify configuration to your liking, here is an example:
$HOME/.config/MangoHud/MangoHud.conf

Install gamemode package:
sudo pacman -S gamemode
Then enable gamemode in lutris settings - either per game or per runner (systemwide).
Allow your wheel user to edit process priorities by adding the following to the limits config:
/etc/security/limits.conf
@wheel - nice -20
Modify configuration to your liking, here is an example:
$HOME/.config/gamemode.ini
[general]
; The reaper thread will check every 5 seconds for exited clients, for config file changes, and for the CPU/iGPU power balance
reaper_freq=5
; The desired governor is used when entering GameMode instead of "performance"
desiredgov=performance
; The default governor is used when leaving GameMode instead of restoring the original value
;defaultgov=powersave
; The iGPU desired governor is used when the integrated GPU is under heavy load
igpu_desiredgov=powersave
; Threshold to use to decide when the integrated GPU is under heavy load.
; This is a ratio of iGPU Watts / CPU Watts which is used to determine when the
; integraged GPU is under heavy enough load to justify switching to
; igpu_desiredgov. Set this to -1 to disable all iGPU checking and always
; use desiredgov for games.
#igpu_power_threshold=0.3
; GameMode can change the scheduler policy to SCHED_ISO on kernels which support it (currently
; not supported by upstream kernels). Can be set to "auto", "on" or "off". "auto" will enable
; with 4 or more CPU cores. "on" will always enable. Defaults to "off".
softrealtime=on
; GameMode can renice game processes. You can put any value between 0 and 20 here, the value
; will be negated and applied as a nice value (0 means no change). Defaults to 0.
renice=8
; By default, GameMode adjusts the iopriority of clients to BE/0, you can put any value
; between 0 and 7 here (with 0 being highest priority), or one of the special values
; "off" (to disable) or "reset" (to restore Linux default behavior based on CPU priority),
; currently, only the best-effort class is supported thus you cannot set it here
ioprio=0
; Sets whether gamemode will inhibit the screensaver when active
; Defaults to 1
inhibit_screensaver=1
[filter]
; If "whitelist" entry has a value(s)
; gamemode will reject anything not in the whitelist
;whitelist=RiseOfTheTombRaider
; Gamemode will always reject anything in the blacklist
;blacklist=HalfLife3

; Warning: Use these settings at your own risk
; Any damage to hardware incurred due to this feature is your responsibility and yours alone
; It is also highly recommended you try these settings out first manually to find the sweet spots

;nv_powermizer_mode=1
; These will modify the core and mem clocks of the highest perf state in the Nvidia PowerMizer
; They are measured as Mhz offsets from the baseline, 0 will reset values to default, -1 or unset will not modify values
;nv_core_clock_mhz_offset=0
;nv_mem_clock_mhz_offset=0
; AMD specific settings
; Requires a relatively up to date AMDGPU kernel module
; See: https://dri.freedesktop.org/docs/drm/gpu/amdgpu.html#gpu-power-thermal-controls-and-monitoring
; It is also highly recommended you use lm-sensors (or other available tools) to verify card temperatures

This fixes nct6687 driver not working properly (cannot set PWM values) in case you have it on your board.
Install nct6687-dkms-git package (need AUR packages enabled):
sudo pacman -S nct6687-dkms-git
Blacklist nct6683 driver:
/etc/modprobe.d/nct6683-blacklist.conf
blacklist nct6683
Install xone-dkms package from AUR.
Then reload udev rules:
sudo udevadm control --reload-rules
sudo udevadm trigger
Just for quick reference, might need to install some packages first:
# show display info
xrandr --prop
# show driver info
vulkaninfo --summary
# show GPU utilization
radeontop
# test if freesync is working
vrrtest
# check if reBAR is enabled
