Considering that I've seen YouTube videos showing a guy pulling a real-life bird out of the emoji icons on the screen, I have issues trusting YouTube videos as "evidence".
Now, show me a reputable testing site, like Tom's or Anandtech, where they've actually tested the game on a dual-core machine (including the hardware they used). But some random guy posting a YouTube video that could easily be edited from other video clips? That's about as reliable as the "I stole your nose" trick you play on a toddler.
