Problems with Gamescope

Hey there. Is someone able to use Gamescope at the moment? I can’t get it to work. Games are just crashing right after launch. This happens with Steam, Lutris and Heroic. I found several issues on GitHub regarding Gamescope, so mabe it is not just me beeing dumb?

Some context:

Launching Steam with Gamescope like mentioned in the Arch Wiki:

gamescope -e -- steam                                  
No CAP_SYS_NICE, falling back to regular-priority compute and threads.
Performance will be affected.

Steam installed like that:

programs.steam = {
  enable = true;
  remotePlay.openFirewall = true; # Open ports in the firewall for Steam Remote Play
  gamescopeSession.enable = true;
  dedicatedServer.openFirewall = true; # Open ports in the firewall for Source Dedicated Server

Lutris installed like that:

environment.systemPackages = with pkgs; [
    (lutris.override {
	    extraPkgs = pkgs: [
      extraLibraries = pkgs: [

Thx :slight_smile:

I’m using it successfully to wrap Wine. I don’t have any experience with Steam etc.
