Kind of a pointless article. They came up with a technique to create the sensation of playing at 60 FPS, despite in reality running at 30 frames. They then explain absolutely nothing about how they achieved that. I got as much from the article as I did the headline on HN.
Yeah it's a real puff-piece, more a thinly-disguised advertisement than it is an article...
This is very clever brain hack, and very interesting to hear.
