Performance Evaluation - Display Performance

Display Performance reports on the number of graphics triangles, excessive image quality, slow display speed, and components that contain a high number of face level appearances.

Each component is checked for the number of tessellation triangles that are required to display the component. Triangles are used to approximate curved faces for displaying a component. A component that contains more curved faces requires more triangles. Triangles must be calculated, stored, and transferred to a graphics card for display.

Image quality can affect the number of triangles as a higher setting for image quality requires more triangles to display components that have curved faces. Components that contain only flat faces are not affected by the setting for image quality.

   
Graphics Triangles Lists files by the number of graphic triangles contained in a part.

In Graphics Triangles Details, displays the total number of graphic triangles in the top-level assembly.

Click Open to the left of a file name to open the file in a new window. You must close the Performance Evaluation dialog box before you can switch to the opened file.

The number of graphic triangles indicate the level of detail in a component. A high number can indicate a component with excessive detail.

Components are not listed when the sum of graphics triangles for all instances is less than 5,000.

Click Show These Files to view a list of files with 5,000 or more graphic triangles.
Shaded Image Quality Lists the files where the image quality is medium-high or very high. Click Show These Files to view a list of affected files.

Reduce Image Quality reduces the shaded image quality to 50% for the parts with higher image quality, and moves the Low (faster) - High (slower) slider closer to the Low (faster) side.

Reduce Image Quality does not apply to subassemblies.

Reduce Image Quality is not available for assemblies opened in lightweight mode except when the assembly has a flexible subassembly.

To view the slider, click Tools > Options > Document Properties > Image Quality. The slider is under the Shaded and draft quality HLR/HLV resolution section,

Parts with very high image quality have the slider set at 80% or greater. Parts with medium-high image quality have the slider set at 60% - 80%.

Parts that have curved faces require more graphic triangles for display when setting image quality to a higher setting.

If the list of files does not appear, click Tools > Options > Document Properties > Image Quality and clear the Apply to all referenced part documents option. A message about assembly image quality appears when you have the Apply to all referenced part documents option selected and meet the following conditions:
  • Shaded and draft quality HLR/HLV resolution slider is set above 60%.
  • The number of components in the assembly is equal to or above the Large Assembly Settings threshold.
Display Speed Indicates if the display speed is too slow during dynamic view operations like zoom, pan, and rotate.

To improve display speed:

  • Use Large Assembly Settings, which is a collection of system settings. Click Tools > Large Assembly Settings to turn on Large Assembly Settings.
  • On the View toolbar, turn off:
    • Shadows in Shaded Mode
    • RealView Graphics
  • Minimize the use of texture:
    • Do not apply textures until you need them.
    • Create a derived configuration of the current model and apply textures to that derived configuration. Edit your model using the configuration that does not have the textures. To display the model with the textures, switch to the derived configuration.
Appearances Displays a warning if a file contains over 100 appearances applied to faces. Click Show These Files to view the list of affected files.
Components Far from Origin For assemblies that have a bounding box larger than 1000 meters, if one or more components are far from the assembly origin then the assembly seems to disappear when you zoom to fit. The assembly zooms far out to include the components near the origin as well as those far from the origin.

Click Fix It to move the stray components closer to the origin.
