Capability Geometry allows to use the Layer builtin in geometry and pixel
shaders. For vertex and domain shaders ShaderLayer should be used, but it's only
available starting from SPIR-V 1.5. ShaderViewportIndexLayerEXT can be used
instead with extension SPV_EXT_shader_viewport_index_layer.
VK_MEMORY_PROPERTY_DEVICE_COHERENT_BIT_AMD and
VK_MEMORY_PROPERTY_DEVICE_UNCACHED_BIT_AMD were introduced by
Vulkan-Headers 1.1.121; we currently require version 1.2.148.
Raises framerate by 5-10% in games which write thousands of descriptors
per frame, e.g. Horizon Zero Dawn.
The worker thread is a generic device worker which can also be used for
other purposes if the need arises.
Fixes a race condition where the descriptor is modified between getting
its object and resetting the `next` index. The new object would never be
written. While it is invalid for the app to write descriptors used by a
command list which has been submitted to a queue, unused descriptors may
be written. This change also supports writing descriptors in a worker
thread.
Because that's the granularity of Constant Buffer accesses in SM4.
This commit requires using more push constants, but without it the
generated SPIR-V can be invalid.
