What's New in Performance

Evaluation Toolkit

The Evaluation Toolkit is a new set of inspection and debugging tools designed to help diagnose correctness and performance issues with your scenes. It is a reworking of the previous Evaluation Manager Debugging Shelf previously available as a Maya shelf and distributed with the Bonus Tools. By making these tools directly available in Maya (Windows > General Editors > Evaluation Toolkit), they are now accessible for anyone interested in understanding the implications of new evaluation modes.

Use the Evaluation Toolkit to speed up animation with features that let you manipulate all aspects of the Evaluation Manager, including enabling debugging modes and output.

See Evaluation Toolkit.

Viewport 2.0 performance improvements

• Control the preview quality of UV tile textures in the UV Editor to avoid waiting for textures to load with full resolution.

  The Preview Quality setting in the file node Attribute Editor now applies to both the UV Editor and Viewport 2.0.

• Materials are not evaluated when they are not visualized in the viewport. You can therefore improve performance by setting objects to wireframe or by hiding them.
• Playback performance is improved by a factor of 2-3 in scenes with hidden objects.
• Screen space ambient occlusion performance is improved when using OpenGL Core Profile mode

• Interaction is improved while materials and textures load when opening a new scene with the Material Loading Mode set to Parallel in the Display preferences.

  The Materials To Load HUD and Textures To Load HUD indicate the loading progress. When complete, the HUD shows 0.

• Memory allocated to textures not used for rendering can be released with the ogs command and drt flag. For example, use this command to free texture memory after switching from textured to shaded mode, or templating or hiding objects. See Release GPU memory for unused textures.

• Selection performance is improved in scenes with a huge number of nodes.
• Selection performance is greatly improved in scenes that contain hidden groups.
