Resource List
All resources are grouped by Input, Execution, and Output stages.
By default, Frame Analyzer shows all resources attributed to the current selection. Use the 
Filter menu to filter resources by type:
- Geometry
- Textures
- Shaders
- Data buffers
- Graphics/Compute Pipeline States
- Samplers
- API call arguments
To filter resources by name, type the desired name or parameter into the Type filter expression field.
Some resources support previews. To see the preview, hover over the resource thumbnail in the Resource List.
Use 
Back and 
Next buttons to navigate back and forth between recently selected resources and events.
For textures, shaders, or geometry, you can choose the following view types:
- Table View
To see resources in a tabular view, click the
Show Resource Table button. To configure table columns, click the
button. To select a resource and open it in the Resource Viewer, click the row with the required resource.
- Tile View
Tile view shows only resource thumbnails. To open tile view, click the
button. Resources can be sorted by resource type, name, ID, or stage. To select a resource and open it in the Resource Viewer, click the row with the required resource.
Resource Notations
Resource names, except texture and buffer names, are abbreviated and shown in the Resource List and Resource Viewer in the following format:
<resource type>:<resource ID> [<user-defined name>]
Texture names and buffer names are shown in the following format:
<resource type>:<resource ID> (<view type><view ID>)
Resources Names for DirectX API

Save Texture to File button - saves a texture image or render target in the Direct Draw Surface (DDS) format, Khronos Texture (KTX) format, or PNG format. 
Flip Image button - turns a texture image or render target upside down. 
Histogram button - opens a For textures with mipmaps, 3D textures, and texture arrays, you can select a particular subresource in the MIP-level selector or the Layer selector:
Grayed-out values in the MIP-level selector or in the Layer selector mean that the corresponding subresources are not defined in the selected resource view.
You can experiment with SRV textures using the following elements:
Texture 2x2 button - replaces the opened texture with a simple 2x2 pixel texture for the selected events. The experiment creates a new texture with the same name and of the same type, and denoted as [modified]. 
Clamp to Selected MIP Level button - disables all mipmaps of the opened textures that are greater than the current mipmap level of the texture for the selected events. The experiment creates a new texture with the same name and of the same type, and denoted as [modified]. - Format drop-down list - shows the original texture format and enables texture format replacement (DirectX 11 only).
To disable the applied experiments, click the 
button on the texture thumbnail in Resource List.
For cube map textures, you can open one face of a cube map by selecting the desired face from the drop-down list. The Default option is a cube map layout.
NOTE:

Shader Table is a tool for deep analysis of ray tracing shaders. The table visualizes all shaders that can be potentially executed as a result of a DispatchRays call. Shader Table also contains performance metrics for each shader.
NOTE:
Shader Table is available for DirectX* Raytracing applications starting with Intel® Arc™ high-performance GPUs code named Alchemist, and previously known as DG2.
When you select a DispatchRays call in Graphics Frame Analyzer, Shader Table becomes available in the Resource List as a separate item. Click the Shader Table resource to view detailed information about shaders:
- Export Name(s) - unique shader names, which are exported from the raytracing pipeline state object and used to generate the shader identifier.
- DXIL Entrypoint - shader name from the HLSL source code.
- Hit Group(s) - names of hit groups where the shader is used. Only closest hit,any hit, and intersection shaders can be included in a hit group. Cells in the Hit Group(s) column are always empty for ray generation,miss, and callable shaders.
- HW Thread Count - number of hardware threads executing instances of a shader. If the number is zero, the shader was bound to the pipeline but not executed. Maximum number of shader instances in a hardware thread depends on SIMD width (8, 16, or 32).
- Duration % - relative duration of a shader, where 100% is the sum of durations for all shaders.
- SIMD Occupancy % - number of SIMD lanes executing a shader, in relation to the total number available across all threads. If SIMD occupancy is low, the hardware scheduler could not aggregate different shader instances in one thread. Developer and Optimization Guide describes how to improve SIMD occupancy.
- SIMD Active Channels - the number of rays processed by the shader. The value of SIMD Active Channels metric equals to HW Thread Count * SIMD width * SIMD occupancy / 100%.
- Type - shader type as defined in the DXIL library.
- DXIL Library - identifier of the DXIL library where a shader is declared. You can use the identifier to find a proper shader code from the Resource List.
Resource Viewer: Buffer
|
Buffer Viewer pane
Offset and Size field - shows the offset value and size of the opened buffer block in the original buffer object. |
|
Buffer Viewer toolbar
Buffer Layout field - enables you to view and edit the opened buffer layout. The layout is written in the buffer markup language.
|
|
Buffer Viewer window Shows the opened buffer details in a table or list format. |
Show Resource in Separate Window button - opens Buffer Viewer in a separate window. 
View toggle button - toggles between the list view and table view of the Buffer Viewer. 
Restore Default Layout button - reverts any buffer layout modifications made by the user and restores the default shader-defined or pipeline state-defined buffer layout or a default format (float4 or xuint4), if the buffer layout was not received from shader. 
Info button - opens the layout editor help with the markup language help. Resource Viewer: Graphics/Compute Pipeline State
The Graphics/Compute Pipeline State Viewer shows settings for fixed function blocks of the graphics/compute pipeline. The settings can be changed.
For DirectX and OpenGL applications, State Viewer shows API-agnostic data. The data can be modified for several draw calls simultaneously:
For Vulkan, State Viewer shows Vulkan-specific data only for one draw call:
For Frame [DX12] and Stream modes, Graphics Frame Analyzer provides a Graphics state item, which is a read-only combined state view that unifies both Pipeline State Object (PSO) and non-PSO states. When multiple calls are selected in API Log this view provides information about all selected calls.
For Frame [DX12] and Stream modes for DirectX 12 and Vulkan APIs, State is an editable layout pane. To edit states select draw or dispatch call in API Log. Editing is supported for a single selected call only.
For example, you can change Fill Mode to Wireframe. The changes are applied immediately. You are able to see the results on RTV (as shown below).
Resource Viewer: Non PSO State
The Non PSO State is an editable pane that is available for DirectX 12 in Frame [DX12] and Stream modes. This pane exposes states that can be set on a command list. You can view and edit the Non Pipeline State Object (PSO) states if you select one or more draw calls or DispatchMesh calls in API Log.
The panel shows Shading Rate for Variable-rate shading (VRS). You can select different shading rates: per draw call or multiple draw calls.
You can experiment with the options to reduce shading rates with little or no perceptible reduction in output quality. Supported shading rates include:
- 1x1
- 1x2
- 2x1
- 2x2
- 2x4
- 4x2
- 4x4
Supported shading rate combiners include:
- Passthrough
- Override
- Min
- Max
- Sum
| No VRS | 4x4 VRS applied |
|---|---|
No variable-rate shading applied, which is the same as a 1x1 shading rate.
|
For 4x4 VRS, one pixel is rendered for each 4x4 group of pixels.
|
NOTE:
For more information about VRS refer to the Microsoft documentation on Variable-rate shading (VRS) .
Resource Viewer: Samplers
|
Sampler Viewer pane
|
|
Sampler Viewer window Shows read-only settings for sampling textures. |
Resource Viewer: API Call Arguments
The API Call Arguments Viewer lists arguments of the selected graphics API function. The viewer shows data only for a single function.
For the DirectX 11 and DirectX 12 frames, you can change arguments to change input geometry, clear color or the number of computing threads.
You can change arguments for the following calls:
ClearRenderTargetView
ClearDepthStencilView
ClearUnorderedAccessViewFloat
Dispatch calls
For DirectX 11, all draw calls except DrawIndexedInstancedIndirect and DrawInstancedIndirect
For DirectX 12, DrawIndexedInstanced and DrawInstanced
Resource Viewer: Root Signatures and Descriptors (DirectX 12 and Vulkan only)
This resource view enables you to explore the internals of DirectX 12 Root Signatures and Vulkan Descriptor Sets. This can be useful for debugging sporadic rendering issues, like a wrong texture being used for an object.
