I’m giving this a shot and having a surprisingly good time with the driving. I bounce off any sim-heavy driving games, including the Horizon games, but this seems to be in my sweet spot. Looks pretty good on Xbox One X too. But oh man, the writing and voice acting is hilariously bad.
I'll just add that I'm having these buffering issues as well. Videos pause and buffer every few seconds. Am experiencing the same issue in both Chrome browser on Windows 7 and the Xbox One app. But, at least as of last night, no issues watching Roku beta app. ISP is Mediacom.
I use the Xbox One Internet Explorer and it works fantastically (though I only watch archived video, not streams.) Just hit play on the video, hit full screen, and go. It's pretty much the only way I watch Giant Bomb these days.
