We're hoping sooner than later thanks to Tobi's bounty on this. You can follow the design spec at https://github.com/obsproject/rfcs/pull/15 if you're interested.

It is really awesome and fast development. I am hoping it ends up cross platform (Linux) and not only OSX specific.

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.

Check out CamTwist in the meantime - that has a virtual camera on Mac, and I enjoy using it to flip my video upside down (because I live in New Zealand). Also for typing large-text subtitles over the image, which was great for my late grandmother. I'm not affiliated, and it's free.

My problem is more like OBS does everything I need, but I need to use OBS as a camera in Zoom or Hangouts, but I suspect CamTwist isn't as feature-rich.

You can pipe OBS through Syphon into CamTwist.
