Packet loss and increased latency are the main symptoms of using more bandwidth than the network can reasonably provide.

In live video, latency from encoding is a limiting factor for what types of compression you can use. Its not like bandwidth is the sole limiting factor here.

I can still see compression artifacts, so it's clearly not using enough bandwidth. It could probably compress it better if it had hardware available, rather than needing to do real-time encoding in software (since it doesn't have a VP9 encoder either).
