Racerrom:

Seems X.org is better
SealHUD ads frametime issues, dont use.
Disable Composer, KDE with wayland seems to never respect that, use X.org with XFCE
On OBS advanced recording setting, set you should have listed Navi 21 VAAPI device (for 6900XT)
Rate Control needs to be CQP at 18 (dynamic,  avoids cornering stutters.)

In my case 0.60 is a good enough fov.

Steam launch:
LD_PRELOAD=/usr/lib64/libgamemode.so.0 gamemoderun mangohud %command%

Workaround to serve brand logos locally(very specific to a test simhub dashboard):
python3.13 -m http.server 8000 --directory /home/srlemke/Downloads/brandlogo & LD_PRELOAD=/usr/lib64/libgamemode.so.0 gamemoderun mangohud %command%

What set and use, 6900XT:

in Settings.JSON set

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

Updated: 26.Nov.2025 - working again after some adjustments!

Reading is annoying some times, but read before start pasting commands.
This installs simhub per game, so you have to install it for each game.

All commands in a terminal as regular user, never as root.

Info: Linux games are isolated 'Compatibility 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 reinstalled.
The vessel for each game has an unique ID.
