I have a project developed using AvaloniaUI, which is probably to render a large image with controllable scaling and render N point icons on the map and draw hot areas, which is rendered using a custom skia renderer, but the performance is average when the point data is large, I am evaluating whether I can use NoesisGUI, I found that NoesisGUI is rendered with dx11 under windows, instead of using the renderer of wpf, Theoretically the performance will be better than the skia?

Noesis can render on Windows using D3D11, D3D12, and Vulkan. While it is compatible with XAML/WPF, it has no dependencies on WPF, our entire codebase was built from scratch without any external dependencies.

And yes, you should definitely expect much better performance than Skia.
