 ------

 Captures have a very limited amount of portability between machines. Many hardware-specific feature uses are baked into captures, and portability depends on how similar the capture and replay hardware are, whether these feature uses can map the same in both cases. Captures are however completely portable between different OSes with sufficiently comparable hardware.

-   Shader debugging is currently only supported on D3D11, D3D12, and Vulkan. On other APIs the debug options listed below will either be hidden or disabled. In addition not all shaders on those APIs can be debugged, e.g. on D3D12 only DXBC shaders can be debugged and on Vulkan only some shader extensions and capabilities are supported. If the shader cannot be debugged the options below will also be disabled.

-Each graphics API has a native shader format - for D3D11 and D3D12 this is DXBC bytecode, for Vulkan this is SPIR-V bytecode, and for OpenGL this is GLSL shader text.

+Each graphics API has a native shader format - for D3D11 and D3D12 this is DXBC bytecode as well as DXIL on D3D12, for Vulkan this is SPIR-V bytecode, and for OpenGL this is GLSL shader text. Additionally it's possible for the bytecode shaders to contain embedded debug information with the original source code and compilation settings.
 
 When editing a shader RenderDoc will display the original source if available, but otherwise it will attempt to invoke a shader processing tool to decompile the bytecode into a usable form. Multiple tools can be configured :ref:`in the settings window <shader-processing-tools-config>` and several for SPIR-V processing come with RenderDoc by default. If no tool is available RenderDoc displays a generated stub or default disassembly as a starting point.
