The tutorial works, but in most of my test on simracing this leads to some kind of stutter.
In general its better to use the default resolutions for simracing at least in my monitor.
If your customm resolution is not for simracing then this totally works.

Needed to find current monitor, Install:
edid-decode

Find your monitor, thats annoying, I know mine is this, yours is probably somewhere in this path to:
edid-decode /sys/class/drm/card1-DP-1/edid

Note, to be able to move widgets in wayland check: "Enable X11 Platform Plugin Override" on tinypedal 
compatibility settings and restart it.

-> Now to install && run:
zypper in python313-pyside6 python313-pyxdg python313-psutil

Clone it recursivelly:
git clone --recursive https://github.com/s-victor/TinyPedal.git

Make sure to place dll from

Install: mangohud gamemode

#You need to unlock the card for over/under-clocking work, add this as grub boot kernel argument:

#To not lose it when updating kernel:
vim /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="mitigations=off amdgpu.ppfeaturemask=0xffffffff"

First, Linux games are isolated 'Vessels' per game, it may look weird, but after understanding it better its quite handy, 
if something goes wrong you just delete the whole 'vessel' and start from scratch, as if windows was resinatalled.

The vessel for each game has an unique ID:
get your game ID with:
grep name ~/.steam/steam/steamapps/appmanifest_*
I will be using ID 1066890 which is for Automobilista2.
Remember, each game is an independ windows-vessel, if you want it on more games you have to install on all game ID's

#Download AMSCM from:
https://www.overtake.gg/downloads/automobilista-2-content-manager.59727/
wine AMS2CM.msi (Do not forget to install CLI that you have to select in the AMS2CM installer)

#Double check the path on the bellow file, this is the most important:
vim /home/slemke/.wine/drive_c/Program\ Files/AMS2CM/Config.yaml
Path: Z:\home\slemke\.steam\steam\steamapps\common\Automobilista 2

#Get the correct refresh rate for the amount of frames/Hz:

-> Bellow is my resolution(5120x1440) and my desired frame cap(165), I want it to display the ideal Hz for that.
I will use the CLI command 'cvt':

slemke@leap:~> cvt 5120 1440 165.00
# 5120x1440 164.88 Hz (CVT) hsync: 261.83 kHz; pclk: 1881.00 MHz
Modeline "5120x1440_165.00"  1881.00  5120 5584 6152 7184  1440 1443 1453 1588 -hsync +vsync

-> Above we can see that the ideal Hz for my resolution@fps is 164.88, so, in my case, we add it to MangoHud config:

Custom Resolution:
Install CRU from https://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU

Extract your current monitor EDID:
cat /sys/class/drm/card1-HDMI-A-1/edid > ~/Documents/my_monitor_edid.bin

Open CRU;
In CRU load the above generated my_monitor_edid.bin (via the import)

#Tutorial Date: 21/05/2025

Follow everything stricly, otherwise wont work. Read every line of this guide.
Nothing needs to be run as root, never.
Best way ATM seems to be install per game.

Preparation:
Download Crewchief.msi
Install wine, winetricks and protontricks on your distro!
