Optimizing Viewport 2.0

You can optimize the performance of Viewport 2.0 by doing the following:

If possible, avoid:

• smooth mesh deformers
• unsupported textures (see Internal texture baking in Viewport 2.0 for more information)
• rigged characters with many input nodes

Optimization tips:

• The Consolidate World functionality consolidates all objects that the camera sees. To optimize tumbling performance, zoom out of your scene view so that the camera can see and consolidate all objects.
• Reuse shaders if possible, especially on small, static objects to optimize the Consolidate World functionality. You can do this by selecting File > Optimize Scene Size > and enabling the Remove duplicate: Shading networks option.
• Use Smooth Mesh Preview instead of smooth mesh deformers for faster performance.
• Unsupported texture types are baked internally in Viewport 2.0. For better performance, avoid using unsupported textures; or, use a low bake resolution in the Renderer > Viewport 2.0 > > Bake Resolution for Unsupported Texture Types settings.
• Select the Simple or Object Sorting Transparency Algorithm under Renderer > Viewport 2.0 > > Performance. The Depth Peeling option provides high transparency quality but with a performance cost.
• Multisample Anti-aliasing and Screen-space Ambient Occlusion (under Renderer > Viewport 2.0 > ) can be disabled for better performance. Enable these options for better visual quality and disable them for better performance.
• When working with the DirectX 11 MayaUberShader, mip map generation is enabled by default to provide better texturing quality for objects far away. You can disable mip map generation to improve performance; however, you may see a moire pattern for far away textures. In the <maya directory>\presets\HLSL11\examples\MayaUberShader.fx file, set #define NumberOfMipMaps 1.
• To accelerate performance, use of Smooth Mesh Preview is not recommended when tessellation is enabled in an effects shader.
• The dx11Shader node supports both uncompiled (.fx) and compiled (.fxo) effects. For large scenes and complex shaders, use only compiled effects.

Performance tips for animation

• Joints render faster if they are all set to the same color so that they can be batched together during rendering.
• Local rotation axis and handles on the transform may slow down performance.
• HumanIK that do not use alpha blending render much faster.
• Vertex animation cache includes a matrix animation cache. When this is enabled, UI elements do not need to recalculate their matrix information and performance is improved when replaying an animation.
• Ghosting uses the matrix animation cache; therefore, you also obtain better performance when vertex animation cache is enabled.
