You joke but having CC open in the terminal hits 10% on my gpu to render the spinning thinking animation for some reason. Switch out of the terminal tab and gpu drops back to zero.
Most people's mental model of Claude Code is that "it's just a TUI" but it should really be closer to "a small game engine".
For each frame our pipeline constructs a scene graph with React then
-> layouts elements
-> rasterizes them to a 2d screen
-> diffs that against the previous screen
-> finally uses the diff to generate ANSI sequences to draw
We have a ~16ms frame budget so we have roughly ~5ms to go from the React scene graph to ANSI written.
What? Technology has stopped making sense to me. Drawing a UI with React and rasterizing it to ANSI? Are we competing to see what the least appropriate use of React is? Are they really using React to draw a few boxes of text on screen?

That sounds like an issue with your terminal more than an issue with CC...
Surely you mean 6fps

I'm just flabbergasted.

And that's why it's taking so much CPU and is a pain to use with tmux.
Ah, the hell site, no click.
