Episode notes
Moving Toward Impeller For Mobile Performance
- Avalonia is evaluating replacing Skia with Google's Impeller for better performance on tile-based GPUs like phones and modern Macs.
- Mike James describes collaborating with the Flutter/Impeller team to adapt Impeller beyond Flutter's assumptions.
Real Production Use On Low Spec Devices
- Mike runs Avalonia on very low-spec hardware including a Raspberry Pi and even a 2002-era 500MHz ARM device in production.
- He recounts optimizing heavily for that customer to demonstrate the framework's embedded strengths.
V12 As Experimental Platform For Backends
- Avalonia 12 ships with SkiaSharp as default but will experiment with Impeller in previews and integrate it into a later stable release.
- Mike frames V12 as an experimentation milestone to test backends and renderers before V13 stabilization.
