Runs at 60fps on latest Chrome for me. I'm on a retina macbook pro 15".
3fps here on what should be a beefy i7 with a relatively recent integrated GPU. Anyone want to comment on what the bottleneck is?
CPU has little to do with it, since most of the heavy lifting is done by the GPU. Maybe that integrated chip isn't enough.
It does depend whether the particles are drawn using shaders or the simpler canvas drawing commands. Without shaders, it would be very CPU intensive. However this site has definitely taken the shader approach.
