i’ve used it exclusively for the past 2 seasons and it’s more than watchable. But i’m mainly referring to watching a single channel. if you split the window, the quality degrades. Also, if you split the screen, then you can’t be “full screen” any more, so the windows for the games were smaller.
So…summary: For 1 game, i’d say as good as netflix. for 4 games at a time, pretty bad.
