I'm excited about this... But I wonder how much resources it requires to stream 720p 30fps into my older Macs without jitter and dropped frames. I had higher hopes on Elgato Cam Link, if it was in stock anywhere, since it does the processing on chip, but it's just speculation since not a lot of people measure performance on these setups either because it all works so well on Windows and/or they have high end machines for gaming (also Windows). Very few streamers/reviwers use Mac as it is underperformant and undersupported in the video streaming arena. It's really frustrating to realize this right in the middle of this "new normal" where webcams and video capture devices are all sold-out globally and one finds himself with a couple of video-worthless Macs.
Ironically Apple came up with FireWire a long time ago to bring (mostly prerecorded) video faster into Macs and now they lag far behind in every aspect related to video. This includes their webcams, which are terrible. Now that's a different story on iOS devices...
