Enscape-level real-time rendering and navigation is far superior to Revit visualization. For the amount that customers are paying for Revit subscription, a comparable level 3-D working environment should come with the software and not require an additional 3rd party plug-in to make the product functional. The holy grail would be an edit-able native Revit 3-D environment with visualization similar to Enscape's feature. That would be a monumental leap in functionality for Architects and designers.
