should be able the set the upload resolution.
When the host machine has a 4k monitor and the client 1080p, the stream is lagging. However, if the host resolution is lower, it isn't. When changing the host resolution isn't an option, I suggest you should be able to change the resolution which is uploaded to reduce lag.
