Oh, one more thing regarding the ssh wizardry (lol!): It’s not that complicated. You can pass your command as last parameter. For example if you want to launch Dorfromantik (which you should btw), you could do it like this:

ssh me@mymachine "steam steam://rungameid/1455840"

That’s the whole magic. Like this it won’t start an interactive shell, but run the command and closes the connection once the command finishes.

A man, a word. This is my gamescope-session.sh

#!/bin/sh

export DXVK_HDR=1
/usr/bin/gamescope --hdr-enabled -e -- /usr/bin/steam-native -tenfoot

I’ve created a /usr/share/wayland-sessions/gamescope-session.desktop for it, so I can launch it from login screen (or auto start it in my case)

[Desktop Entry]
Name=Steam Big Picture Mode
Comment=Start Steam in Big Picture Mode
Exec=/home/chaser/bin/gamescope-session.sh
Type=Application

In theory this should run all games, that support hdr in hdr. At least Cyberpunk does.

If I remember correctly I had to give gamescope a flag to enable hdr at all. However there was an env too, to tell the windows games through proton, that the machine supports hdr. I’ll check my scripts later for you

+1 for Lutris! It’s not only good for games, but also for regular Windows software like FL Studio. Another “tool” I use a lot is ssh. I use Gamescope on my PC with Steam Big Picture mode. Gamescope gains a few more fps, than a regular de. Also HDR works just fine with it. See: https://wiki.archlinux.org/title/Gamescope However. Sometimes I need an desktop environment. So I created a Home Assistant automation, that allows me to switch to desktop. Now I have 2 buttons on my smartwatch. One to boot the PC and turn on the tv, avr, etc. The other for the desktop mode. I also have some nfc cards for my favorite games. Same thing here: When scanned they trigger a ha automation, which starts the games over ssh 😎
