Oh what the hell, you can't change the quality to 720P from this post? My fellow gamers, do yourself a favor and click this link https://www.youtube.com/watch?v=BGhLRezM_C8, then the youtube wheel to change the video resolution to 720P and higher. Note the game is only 720P though, so 1080P may not be worth it if your interenet is slow.
And if your internet is slow currently, at least put the quality to 480P.
Edit: You can change the video quality when you click play. Do yourself a favor and click the 720P resolution after you click the YouTube wheel setting.
