This is an old video. It might have commentary now, but this was posted months ago. Like I said before, the framerate drops are noticeable, makes a decent looking game look ugly.
*edit*
I'll edit that last part about, not because I don't believe it, but people will take it to mean it looks the same.
Also when he gets to the boss at the end, it's the same including commentary. Not just the same video.
