Hello All,

I use swiftshader to provide an OpenGL environment for skia's GPU rendering mode. I found that rendering time is not significantly reduced when multi-threaded rendering. There is a problem of thread waiting when checking stack information with breakpoint debugging , as shown in the figure. Rendering time is reduced when multi-process rendering. It is in line with expectations. Does swiftshader support multi-threaded rendering?

Hi Kevin,

Thanks for your interest in SwiftShader. First things first, I notice that you're using SwiftShader's OpenGL ES build. Please note that this is deprecated and will be removed soon. We are replacing it with "SwANGLE", a combination of the ANGLE project and SwiftShader's new Vulkan implementation. Skia will integrate support for SwANGLE as part of http://crbug.com/skia/10281.

That said, SwiftShader does not currently perform multi-threaded compilation of shaders, but does execute them on multiple threads.

Kind regards,
Nicolas
