## Description

This extension enables applications to use multisampled rendering with a depth/stencil sample count that is larger than the color sample count. Having a depth/stencil sample count larger than the color sample count allows maintaining geometry and coverage information at a higher sample rate than color information. All samples are depth/stencil tested, but only the first color sample count number of samples get a corresponding color output.

## New Structures

If Vulkan Version 1.3 or VK_KHR_dynamic_rendering is supported:

- Extending VkCommandBufferInheritanceInfo, VkGraphicsPipelineCreateInfo:

  - VkAttachmentSampleCountInfoAMD

## New Enum Constants

- `VK_AMD_MIXED_ATTACHMENT_SAMPLES_EXTENSION_NAME`

- `VK_AMD_MIXED_ATTACHMENT_SAMPLES_SPEC_VERSION`

If Vulkan Version 1.3 or VK_KHR_dynamic_rendering is supported:

- Extending VkStructureType:

  - `VK_STRUCTURE_TYPE_ATTACHMENT_SAMPLE_COUNT_INFO_AMD`
