JUCE Painting Performance Still Needs Improvement

I’ve noticed that FabFilter plugins can handle a much larger number of rendering commands simultaneously. You can try using Pro-Q and see how smoothly you can manipulate all 24 filters, which involves a considerable amount of rendering.

I strongly suspect this is achieved with hardware accelerated rendering such as OpenGL, Metal, Vulkan, etc.

What platform(s) are you running / testing on?

For macOS I’m not sure there is a whole lot of room for improvement, on Windows improvements are being worked on in the form of using a Direct2D renderer (see here for more details).
