On systems with sufficient
            memory and graphic cards, Viewport 2.0 provides large
            scene performance optimization and higher quality lighting and shaders.
            It allows for high interactivity: you can tumble complex scenes
            with many objects as well as large objects with heavy geometry. 
         
         To switch to Viewport
               2.0, select 
                     Renderer > Viewport 2.0 from
            the Panel Menus.

            Viewport
                  2.0 supports the following features:
            
            Viewport interaction
               
               
                  - manipulators: move, rotate, scale
                  
 
                  - object selection
                  
 
                  - locators

                  - perspective and all orthographic views
                  
 
                  - Look Through Selected
                        Camera view
                  
 
                  - mono cameras
                  
 
                  - camera settings such as Film
                           Gate, Resolution Gate, Safe
                        Action and so forth
                  
 
                  - Object Transparency
                        Sorting
 
                  - Playblast 
                  
 
                  - object based Isolate Select
 
               
               NoteFor the best performance
                     and scalability, switch to Viewport 2.0 without enabling
                     texturing or shading in any of the other workspace modes. You should work
                     with only one workspace panel displayed in Viewport
                        2.0 and avoid switching between workspace modes.

                              NURBS > Fine smoothness levels are supported. (This
                           is equivalent to using the 1, 2, 3 keys.)

                     NoteIf an object does
                           not have a shader assigned, or is assigned a shader that is not
                           currently supported, the object appears shaded in the scene view with
                           a bright pink color. If a shading network error occurs, the object
                           appears shaded in the scene view with a red color.
                        
                      
                     NoteAll other shaders
                           not listed above, including 3d textures, are currently not supported.
