Select Viewport
               2.0 for a high performance scene view that optimizes
            large scenes. It allows you to interact with complex scenes with
            many objects as well as large objects with heavy geometry.

            These are descriptions
               of the options in the Viewport 2.0 Display
                  Options window. 
            
            NoteMemory issues are
                  more likely to occur if you are using a 32-bit version of Maya.
                  Scene sizes supported on 32-bit systems, or systems with less than
                  4 GB of memory may be limited.
               
             
            Performance Parameters
               - Consolidate world
 
                     - 
                        
This option attempts
                              to combine geometry caches for shapes using a common material. In many
                              scenes, this can produce a significant improvement in performance
                              at the cost of additional memory. 
                           
                           This option performs
                              a memory check. If you are at risk of running into memory issues,
                              you will see a warning as follows:
                           
                           "There
                                 may not be enough memory to load the scene into Viewport 2.0 while
                                 consolidated world is turned on."
                           TipIf the scene view
                                 becomes unstable, try disabling this option.

                                 incur slight delays when using this option.

Select this option to
                              increase performance by combining transparent objects.
                           
                           NoteSelecting this option
                                 disables Object Transparency Sorting.

                     - 
                        
Selecting this option
                              in scenes that contain instancing may increase performance if sufficient
                              memory is available.

                                 compromised if you select this option and sufficient memory is not available.

                     - 
                        
This option disables
                              re-triangulation on deforming meshes, overriding the Reuse Triangles setting
                              on individual shape nodes. Enabling this option can increase the performance
                              of deforming objects in the viewport.

Use this option to set
                              the maximum number of lights that are used in rendering. Hidden
                              lights are not included. The default is 8 lights and the maximum
                              is 16.

                              are supported as baked textures. You can set the resolution for
                              baked 2D textures using these attributes.

                                 scene or press the Apply button and modify the
                                 attributes of the 2D texture in order to see the effect of the change
                                 on currently loaded textures.
