If I want to watch a livestream, the picture always falters. I have a very good line so should actually be 720p or 1080p no problem. But on Twitch I can only switch to 160p to look fluid. In retrospect, if the video is available, I can easily watch HD. Why is that?
How good is your "very good management"?
Very good is relative
200K line
200K line
And what does a speed test say, how much of it really matters?
