Hello @hsauro! How are you? I'm glad you're using the library.

I came here because I would like to add a note:

This madelbrot test does not reflect the actual speed of Skia4Delphi, in fact, it is only measured reading and writing pixels. The fastest way to draw a madelbrot is to use the GPU as the Skia backend. We haven't done any examples of how to use GPU in Skia backend in VCL version yet, but we did in FMX version.

So, based on Skia4Delphi for FMX (which renders with the GPU), I made a small demo of how fast this drawing can be using Skia4Delphi v3+: mandelbrot.zip

Results:

The first draw is slower as there is a GLSL compilation and code initialization on the GPU. The next draws are much faster, even after resizes (which would rule out the internal cache hypothesis).
