@DJGummikuh On Bazzite (at least on KDE), you will want to install Mission Center, maximize, then watch your GPU(s) for activity. When you launch a Steam game, VGA switcheroo does it's magic. On Bluefin, Mission Center is pre-installed. Alt-tab out of the game will allow you to see which GPU is active - but out of the box, the fact that Helldivers 2 runs full screen, almost maxed out, is an indicator of dGPU usage. ;)
