I'm not actually sure what resolution gets passed through the USB cable. I would assume it's either native resolution or at least 1080. But to be fair I'm mostly recording in 720p 50fps, since the 4k is cropped with the EOS R and I felt more fps is better for webcam footage (the other modes are capped at 30fps (25?) or have a crop). Besides, people don't need to see my face in more detail.

I haven't seen any noticeable delay in the footage so far, but now that you mention it, I'll definitely keep an eye on that.

The EOS R can draw some power from USB, but it doesn't seem to be nearly enough, or it doesn't work while recording or something.
