The Performance Window

The Performance Window is displayed in the 3D Preview Control (when activated) in a browser or in any of the client modules of DriveWorks.

It can also be displayed when editing a DriveWorks 3D document by selecting Display Performance Window from the command bar.

It gives key information about the 3D model being displayed. This allows causes of lag in a 3D scene to be diagnosed.

The values given will differ depending on if it's being viewed inside a 3D Preview control in Administrator or in a browser, this is due to differences in how DriveWorks 3D is rendered.

The information shown includes:

• Counts

  Shows the following:

  • Lights - The number of lights rendered per frame
    • Directional Shadows - The number of directional shadows being cast.
  • Sprites - The number of sprites rendered per frame
  • Decals - The number of decals rendered per frame
  • Decal Batches - The number of decal batches used to render decals per frame
• Performance Statistics

  Shows the following:

  • FPS - Frames per second
  • Scene Size - The overall size of the scene

    When viewed in the DriveWorks 3D Document the scene size will include editor sprites (such as lights and cameras).

    When viewed in a DriveWorks 3D Preview Control (on a user form) these sprites are not visible and the scene size will reflect this.

  • Draw Calls - The number of times the CPU instructs the GPU to draw something per frame
  • Vertices - The number of vertices rendered per frame
  • Texture Bindings - The number of times the CPU uploads a texture to the GPU per frame
  • Shader Swaps - The number of times the CPU instructs the GPU to change active shader per frame
• Optimizations

  This displays all the optimizations that DriveWorks has performed on the 3D Document.

The values displayed will update on a per frame basis.
