Pane: Resources

Displays all resources used by the selected graphics API functions.
Displays details about the resource selected in
Resource List
.
Resource List
All resources are grouped by
Input
,
Execution
, and
Output
stages. Groups with multiple resources are folded. Click the
Show All Resources
button to display the
Resource Table
with all resources in these groups. To close the
Resource Table
, click the
Show All Resources
button again or the
Close
button.
To filter resources, type the desired name or parameter into the
Type Filter Expression
field.
You can use the
Type Filter Expression
field, to find specific resources by running Graphics Frame Analyzer plugins .
For textures, shaders or geometry, you can choose one of the following view types:
  • Table
    view: Shows all available information for all the available resources of the selected events. Click the button to configure table columns. Columns can be sorted alphabetically or numerically. To select a resource, click the row with the required resource. To open the Resource Viewer for the selected resource, double-click the selected resource row. To restore the default view, click the
    Revert to Default
    button.
  • Tile
    view. Shows only resource thumbnails. To open the Tile view, click the button. Resources can be sorted alphabetically or by resource parameters.
You can view all resources or any of the following groups:
  • Geometry
  • Textures
  • Shaders
  • Data buffers
  • Graphics/Compute Pipeline States
  • Samplers
  • API call arguments
To view details about any resource, click the corresponding resource thumbnail in
Resource List
. At the same time, all of the events that use the selected resource are underlined in the
Main
bar chart. When issues exist with the resource, a warning marker displays on its thumbnail:
If your target platform supports the EU Active and EU Stall metrics, the GPU duration for each program is visualized in pie charts:
The full circle of the pie chart represents GPU duration of all the draw calls where the program is used. For multiple API call selections that use more than one program, the size of the pie chart correlates with the GPU duration values displayed on the pie chart. Inner sectors of the pie chart represent the GPU time distribution between active time (green), stall time (purple), and idle time (grey).
To analyze GPU duration for a program, hover over the pie chart to view details on EU Active, EU Stall, and EU Idle timings. Each state receives a highlight outside the pie chart, and you can see the corresponding metric value, measured in microseconds:
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:

Render Target State
drop-down list - toggles between the
following modes
of the selected render target:
  • Normal Mode
    - shows the render target state for the last event, which writes to this render target before reading the render target or before the opened frame end.
  • Scrub Mode
    - shows the render target state for the last selected event.
Output Texture Visualization Mode

  • Current
    -
    shows the render target with modifications. If no experiments are applied, the current state is equal to the original state.
  • Original
    - shows the render target without modifications.
  • Diff
    - shows the difference between the current and original modes.
  • Overdraw
    - shows the render target with a bluescale overdraw visualization. The brighter the color, the more times the pixel was updated. Hover over the pixel to see the hit count below.
Selected Calls
drop-down list - switches between the following ways to render the selected calls:
  • Original
    - renders all selected events with no modifications.
  • Highlight
    - sets all selected events to a pink solid color fill mode.
  • Wireframe
    (only for DirectX 11, DirectX 12, and Vulcan)
    - shows all selected events in a pink wireframe mode.
  • Hide
    - does not show all selected events.
Other Calls
drop-down list - switches between the following options to show non-selected calls:
  • Original
    - renders all non-selected events with no modifications.

NOTE
Selected Calls
and
Other Calls
viewing options apply only to the draw calls that render into the selected render target.
Save Texture to File
button - saves a texture image or render target in the DirectDraw 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 color histogram
of a texture or render target.
Texture Viewer
window
Shows a texture image or render target.
To view the color data of a texture or render target, select it from
Resources List
,
and then click the button to open the color histogram:
  • Select the color range that contains the data you are interested in by clicking and dragging with the mouse pointer in the histogram, or by typing its threshold values in the
    Range Selector
    below the histogram. Graphics Frame Analyzer ignores the values outside the selected range, rescaling all the pixel values to fit the original range. You can also zoom in or out of the selected range using the mouse wheel, and scroll left or right by clicking and dragging the mouse while holding
    Ctrl
    .
  • Switch between the available texture channels for better visualization.
  • View detailed information about pixel values below the histogram:
    • Original values used to store pixel information in memory. This data is in a more precise format than the information provided below the image.
    • Normalized values used in shaders.
  • Return to the default range by clicking the
    Reset
    button. For floating-point texture formats, the default range is [0, 1]. For integer formats, the range spans from the minimum to the maximum possible value. Each color channel has its own [min, max] default range.
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.
For SRV textures of DirectX 11 applications the Texture Viewer features the following additional buttons:
  • 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 mip-maps of the opened textures that are greater than the current mip-map 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 button - shows the original texture format and enables the
    Texture Format Replacement
    experiment.
    Texture Format Replacement
    experiment allows you to change the selected texture format to another format from the drop-down list, if available.
These experiments help to define whether the selected texture bottlenecks the sampler module. If a sampler block is underlined red or yellow in a Hotspot mode, or if you assume there is an issue with texture sampling, in case the Hotspot mode is unavailable; these experiments can help identify the textures causing issues to eliminate these bottlenecks.
Texture Format Replacement
experiment, the
Texture 2x2
experiment, and the
Clamp to Selected Mip Level
experiment can be combined.
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
Cube map layout for a MIP-level, where a face size is greater than 4096px, is unavailable.
