Woah, I was gonna ask if anyone knew when Display Capture was gonna be possible on macOS Catalina again, but when I opened OBS now, I see that it's actually possible in version 24.0.6 that I am running. Guess I must've overlooked it until now the last few times I looked for it, lol.
Anyway. Does anyone have any recommendations for settings to use in order to avoid lots of frame dropping and OBS making other applications sluggish when I try to stream to Twitch? I'm using a MacBook Air Retina 2018 model with an external monitor connected to it.
