It's so sad to see this kind of stuff. It's not like the Galaxy S4 is a slow device. It reminds me of Nokia used a fake video [1] to sell the Lumia 920, which was supposed to have a pretty good camera. It just ends up being an unfortunate distraction that causes people to mistrust you.

Ars is right that this isn't new. I remember ATI being caught in the Quake/Quack thing [2] a dozen years ago.
