Wonder when the vulkan backend will be ready for OpenGL ES 3.0+ !

[梁蕴锋]

Hi, all

     Angle is a greate project, thanks to all the developers, good job! 

     I am just curious about the Vulkan backend of ANGLE, Could anyone tell me when the vulkan backend for OpenGL ES 3.0/3.1 or even 3.2 will be ready?  Is it in near future, or is there any specific timeline of it?

     Also, I am interersted in the performance of the vulkan backend. How does it perform compared to other backends, d3d11, opengl, etc, in terms of FPS and resource usage.

 

Best regards.

Hi Liang,

We're aiming to have 3.2 mostly complete by the end of next year. Currently we pass 3.0 conformance and we're at something like 99% conformant on ES 3.1. So you should be able to try out 3.1 right now on Linux, Windows and Android.

We don't have a good story on performance right now. It highly depends on the benchmark. For basic 2.0 use cases we're pretty good. Generally for most simple games our CPU overhead is fairly low relative to the total frame time. The Vulkan back-end should be able to reach lower overhead than our other back-ends.

Cheers,

Jamie

Thanks for the update. Also I am curious about the timeline about ES 3.2 support for both dx11 and opengl backends. 

My guess is that, ES 3.2 support for opengl backend is relatively easier than other backends, once the common angle frontend is completed. Not sure if it's true.

I already see the status of the ES 3.2 support for opengl backend is "In Progress" now, can it be expected to be completed before other backends? 

What's the timeline in plan for ES 3.2 support for these backends.

Best regards.

It's unlikely we will ever support ES 3.2 on D3D11, there isn't currently a use case for it.

OpenGL/ES is in progress but no ETA, it's not high priority but we will implement it as we add ES 3.2 support for Vulkan.  Our current priority is Vulkan performance.

Our priorities around 3.2 shifted so we don't have a timeline for 3.2 support any longer. As Geoff said we're shooting for better performance vs native right now and finishing up 3.1 support. All this is for the Vulkan back-end only. D3D11 is mostly in maintenance mode.
