Description

There is a large performance gap between SkiaSharp and equivalent native Skia C++ code. The C++ version achieves around 120 fps while the managed SkiaSharp code achieves less than 10 fps by default, and up to 40 fps with new OpenGL flags. Benchmarks and sample code are available below.

Expected Behavior

SkiaSharp rendering performance should be much closer to that of native Skia for equivalent rendering workloads, ideally within 80–90% of the native C++ performance.

Actual Behavior

SkiaSharp rendering is much slower than native Skia, showing frame rates <10 fps in default configuration and around 40 fps with new OpenGL flags, compared to 120 fps for native C++.
