the qobuz webapp is hi-res too, I just use it in Firefox and my dac reports the same bit/sample rate that qobuz does. AFAIK there’s no compression there though I haven’t extensively verified that, only that the end result is 24bit/192kHz if that’s what qobuz says is playing.

EDIT: Also, qobuz is nice because there’s very few things you can click on in the web interface which cause the music to stop playing. I really appreciate that feature… looking at you bandcamp…

Ah, I should have been more clear. The CRITERIA section of the sway documentation states that class matches support regex, so instead of using a * as you did in your example you’d use a regex any .*. So I think (untested of course) that for_window [class="steam_app_.*"] allow_tearing yes should work.

The comment in the code for allow_tearing notes that it must be enabled on the output as well. Here is the relevant output documentation. There are several other notes/recommendations there as well you should probably pay attention to.

Are your games all wine/proton games? For me in sway they all have the same class followed by some uid thing:

] > swaymsg -t get_tree
[...]
  #92: output "DP-5"
    #70: workspace "21"
      #126: con "Automobilista 2" (xwayland, pid: 171976, instance: "steam_app_1066890", class: "steam_app_1066890", X11 window: 0x5400001)

Or gamescope:

] > swaymsg -t get_tree
[...]
  #92: output "DP-5"
    #70: workspace "21"
      #124: con "Assetto Corsa" (xdg_shell, pid: 170694, app_id: "gamescope")

EDIT: Also allow_tearing was added to master 3 weeks ago, so this is definitely not in the current release. FYI to anyone who might try it.
