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.

60fps is pathetic for a TUI when most terminals worth their salt are GPU accelerated and displays can be up to 240fps or even more. But let’s be real if I can play Quake at >500 fps they have no excuse.
