Hi. I have the same issue here.
The computer is a I5 Intel core with 4 ggis and It ONLY runs Broadcam.
Internet connection is cable at 11.32 Mbps
the stream is ok from an android cell
abysmal from a pc browser, even when from local network
and the CPU is topped at 100%
as soon as i shutdown broadcam, the cpu comes back
as soon as i restart broadcam, the cpu goes back up to 100%
what the.... ?
