Parallel Rig Evaluation with new Evaluation Manager
The Evaluation Manager is a new parallel evaluation system that helps increase the speed of both playback and manipulation of character rigs. The new system is multithreaded to take advantage of the computing resources available (cores and graphics processors). Previous versions of Maya included only a single evaluation system (DG mode).
Parallel mode uses the Evaluation Manager to perform parallel evaluation across all available cores.
Serial mode uses the Evaluation Manager, but limits evaluation to a single core (serial evaluation) and is used to troubleshoot correctness issues.
GPU Override is a mode that works with the Evaluation Manager to accelerate deformations if either Serial or Parallel modes are selected. GPU override works with Viewport 2.0.
Evaluation Manager option in the Heads Up Display
A new Evaluation option in the Display menu (Display > Heads Up Display) lets you compare performance gains with the new evaluation modes. See Heads Up Display (HUD) Options.
Exclude nodes from evaluation
A new node behavior, Frozen, lets you temporarily disable the evaluation of problematic nodes by the Evaluation Manager. Problematic nodes create playback slowdowns, and disabling them can increase performance.
The Profiler lets you locate performance bottlenecks in your scene by recording and demonstrating in a graph the amount of time that each process consumes.
