Interesting, I wonder how good Impeller is and if it's actually better than the new Graphite backend of Skia.
the big difference is this
Predictable performance: Impeller compiles all shaders and reflection offline at build time. It builds all pipeline state objects upfront. The engine controls caching and caches explicitly.
Flutter’s Impeller renderer outperformed Skia. Impeller eliminates runtime shader compilation stalls, delivering lower frame times and more stable performance. For animation-heavy, graphics-rich apps, enabling Impeller significantly reduces jank and provides a smoother user experience.
