When ANGLE RendererVk can support GLES3.2

[Stevenley Huang]

Hi,

Would you help on where I can find the schedule of OpenGLES3.2 support in Vulkan backend?

Hi,

There's no strict schedule that we could share, but we are nearing the finish line. Most GLES3.2 CTS tests pass already, and most GLES3.2 applications already work. There are some Vulkan vs GL compatibility issues that we are working through with Khronos, and those may take longer to get resolved (but again, likely not something any real application would actually depend on). You might be interested in the `angle_expose_non_conformant_extensions_and_versions=true` build flag that enables some extensions that mostly work except for corner cases. It also exposes ES3.2 even if some of the less used functionality is not done yet.

Hi Shahbaz,

Thanks for the detailed information, and glad to hear that, and  I will try to get the latest code and build it with flag '  angle_expose_non_conformant_extensions_and_versions=true' to see if any issue.

Sorry for the  late response as I asked leave these days :)
