General

• Improvement with MDGContext matrix evaluation: evaluating of multiple matrices within the same frame time is improved.
• Two new options have been provided to improve performance with Viewport 2.0: Vertex Animation Cache and Thread Dependency Graph Evaluation. See Renderer > Viewport 2.0 for more information.
• Performance optimizations reduce save times for Maya Ascii (.ma) files, particularly for scenes containing large meshes.

Dynamics and nDynamics

• Improvements to Fluid Effects includes enhancements to the interactive draw and fluid output meshing. See What's New in Fluid Effects.
• Additional Nucleus solver threading improves the performance of playing back nCloth and nParticle simulations. See What's New in nCloth and What's New in nParticles.
