Display and User Interface Components

• Improved display performance for geometry due to additional multithreading.
• Faster tumbling of textured and trimmed surfaces.
• Faster textured display for a large number of objects.
• Faster textured display for a large single object with multiple UV sets.
• Faster tumbling of lit polygons with a single UV set.
• Faster container node creation when the hypergraph window opens.
• Opening the hypergraph window in the presence of a container with a large number of nodes is much faster.

Animation

• Faster ghosting for scenes with rigs.
• Substituting geometry ( Skin > Edit Smooth Skin > Substitute Geometry) is faster when you are replacing a low resolution model with a high resolution model.

Deformers

• The lattice deformer is now multithreaded.
• Optimized blend shapes.
• Optimized cluster deformers.
• The wire deformer solver is now multithreaded.

Dynamics and Effects

• Improved rewind speed for scenes with multiple nCloth objects.
• Optimized fluids emitter.
• The Fluids surface emitter is now multithreaded.
• Much faster performance of degree 1 NURBS curves in Paint Effects.
• Hair collisions with constraints are faster.
• Rewind performance for scenes with large numbers of nCloth objects has been improved.

Rigging

• Muscle sliding contraints are faster.

Modeling

• Polygon UV smoothing is now now better multithreaded to improve performance on systems with 4 or more cores.
• Editing operations such as sculpting, soft modification, and Soft Select are now faster when you are using the Smooth Mesh Preview mode. (See also Smoothing polygon meshes.)
• Querying your scene for blind data using the polyQueryBlindData command is now much faster, particularly if you are working with large meshes. (See also What is blind data?)

General

• Files that contain a dynGlobals particle node load faster.
• Improved performance of large scenes on 64-bit Linux operating system.
• Improved performance in several areas of math-intensive code on 64-bit Windows operating system.
• Saving a file ( File > Save Scene) is faster when referencing a file that references a large number of files. See also About file referencing.
