I use the obs studio automatic scene switcher plugin and have found it to work fine with chrome tabs and many other games (csgo, tf2, civ v, civ vi, tabletop simulator) but for some reason it never works with Fortnite. I don't know what's different about this game but I've tried running it in both windowed and fullscreen mode to no avail. The other issue is that for some reason when I do manually switch to the fortnite scene, it will usually start out as all black and the game capture doesn't get anything. I then swap back to my desktop scene with monitor capture and it shows fortnite fine, then I'll swap back to the game scene and it will usually work (sometimes I have to repeat a few times). I'm thinking there must be something different with how the game works that is messing with it. Because I don't have the stream overlay I suppose I could just have it be desktop capture but sometimes it shows the taskbar and it won't go away and other stuff can come up and be distracting
