Why are games single-core bound on CPUs and not multithreaded? I understand why the rendering is offloaded to GPUs but what about other tasks?

You: *Hey CPU-1, I need you calculate how high and far the character jumps in the current gravity.*
CPU-1: *Ok*
You: *Hey CPU-2, while CPU-1 works on that I need you to calculate the new position of the character after jumping*
CPU-2: *ok… Hey wait, how high and far did the character jump?*
You: *I don’t know ask CPU-1…And have you seen CPU-3? I need to know if the character touched lava after jumping…*
CPU-3: *bitch I can’t do math on shit that ain’t happened yet wtf you want me to do?*
Hopefully, this demonstrated why it doesn’t really help to add more CPU’s to the equation.
