Kinda crazy that it takes 50 million steps to show me a pixel on the screen for a modern video game. (Of course, most of those steps are re-used when showing the other 2 million pixels, and many of those steps are "wait for a slower thing", but still...)

In one of our videos, one of the question regarding cpu cycles and speed was could mouse movement have any noticeable effect. And we did some back of the envelope math where during a very fast mouse movement, there would be millions of cpu cycles. Kinda blew the other guys mind.

Nah its mostly multicore now. CPU can do the physics, but it's often batched up and send to the GPU. CPU is often doing the mundane tasks (which there are a lot) and then creating batches of commands for the GPU.
