The Tanks demo makes my CPU hurt (15" rMBP, Firefox).

Why is WebGL still so heavy on the CPU?

It works fine on my 2011 15" macbook pro with Firefox 54.0b4. I wonder if it is the high retina resolution thats the problem for you?

It might be because the macbook is also driving a 4k display at the same time.

It takes up about 2 percent of my 7 year old cpu in chrome. It is also compiled from Unity, so was not made from C++ directly.

Apple's OpenGl support is crap.

Well, how else are we supposed to get nice side channel / timing attacks?
