No Feral Game Mode option in the settings for games that run natively on linux.
All my games on Heroic have the option to enable Feral Game Mode except for the one native linux game I own which happens to be Slime Rancher. I've tried to manually add the launch option to the game in Heroic like you would in Steam (gamemoderun %command%) and even tried plain (gamemoderun). I've searched on this channel, the website, as well as google to find out if I was doing something wrong and can't seem to find anything as silly as it is. I was able to add the game to Steam and use it's launch options (gamemoderun %command%) as a workaround but I'd prefer to keep Heroic games in Heroic if possible. I've added my Heroic log as a just in case although it doesn't seem too helpful.
