- create a shortcut link on desktop for the specific game in epic launcher
- Go to the properties of this shortcut and copy the url For Tony Haw's Pro Skater 1+2 its: "com.epicgames.launcher://apps/Guppy?action=launch&silent=true"
- Go to steam and add a non steam game to your lib
- Search for '''cmd.exe'''
- Change the launch properties to /k start com.epicgames.launcher://apps/Guppy?action=launch^&silent=true & exit
- Change the name and icon if you will
- done
With these steps, it was possible to use the steam controller and overay in Tony Hawk's Pro Skater+ 1+2.
This is the answer, thank you so much. I was trying to run a game while the Epic Launcher was already running and closing it first solved it. I like to utilise Steam's recording and this is working now. Only issue is that you have to have the audio capture set to all system audio in Steam's settings. Not just the game application. I think because it's still trying to get audio from the launcher rather than the game. But no biggie.
