Your broader point is well taken but I thought I'd stop by with some trivia. High end engines such as unreal will rasterize absurd quantities of micro-geometry manually using compute shaders in order to avoid the bottleneck of the hardware rasterizer.

High end engines such as unreal have the excuse of being tasked with rendering millions of polygons, in which case a complex approach makes sense. Claude Code is only being asked to render a few thousand UTF-8 characters.
