I think i might have solved it for me on Asus Maximus VIII Hero (I219V) - i've manually installed I218V (20.2 version) driver and for the last couple of days i didn't have any issues apart from "normal" huge stuttering when downloading something at full speed in utorrent. I can watch youtube videos and browse just fine without latency issues.
I'll post again if the issue appears. The latest driver (Version:20.7.1) definitely didn't work for me though.
