Figma cut vector editing time by up to 10x for complex illustrations and icons with thousands of vertices. Software engineer Lauren Budorick identifies six specific optimizations responsible for the gain: instanced rendering, a fast path for drawing selected segments, hit testing improvements, stroke options and box selection handling, and faster gathering of selection colors.
The breakdown is technical and specific. Each optimization targets a discrete bottleneck in how Figma processes and renders vector data at scale. This is not a feature announcement. It is an engineering postmortem on performance, and the specificity is what makes it useful.
If you work with dense vector assets in Figma, or you build graphics tools yourself, the full video is worth watching for the implementation logic behind each fix. Budorick covers all six in under two minutes, which means the signal-to-noise ratio is unusually high.
