Seems to max out my CPU on MBP macOS Sierra Chrome 56.0.2924.87 (64-bit)

That's really surprising. I have no problems on my win machine which I guess is why I missed it.

Is it the same problem even if you run it in backgorund? Have some listeners that will pause the youtube video when that happens (which should minimize CPU)

For me the high CPU usage seems to happen because of the video background. As soon as I remove the <div class="video-background"></div> the CPU usage drops to normal on my MacBook Pro (with integrated GPU)

Could be the background clouds video + software rendering.

Try taking out <div class="video-background"> and see what happens.

Thanks for the leads. Will rewrite it to use PNGs and CSS animations instead of the youtube video! :) This is all a learning journey for me, so it fits right in! :)

Same issue here! Otherwise great work, really cool!
