Use vcc instead, probably the most promising development in the field so far.

> Looks great but also probably not production ready More production ready than Clang-HLSL's SPIR-V backend :P

I think on Vulkan @krogovin you could use subpass input + EXT_fragment_shader_interlock to achieve a gl_FramebufferFetch Normally you can only use a subpass input in the same way as on...

I've actually ran into this issue with Vulkan https://github.com/KhronosGroup/Vulkan-Docs/issues/1649 Seems like its the only case when OpenGL + GLES can result in more features & performance than Vulkan.

going from 0.11ms to 2.11 ms with interlocks is natural if the GPU is highly parallel (you've thrown a 5700 XT with ridiculous 2560 shading units at it), and you're...
