Performance
Do you set Auto only on memory limit? We do have some supermodelse and it doesn't have a performance difference from my old 32-bit XP 3GB switch with 4GB workstation and 64-bit XP 16GB memory workstation.

The basis of Autodesk NavisWorks Manage 2009 is its ability to walk through any size model in real time. NavisWorks guarantees a user-defined frame rate using a unique algorithm which automatically calculates which items to render first during navigation, based on the size of items and distance from the viewpoint. Items which NavisWorks does not have time to render are, therefore, sacrificed or "dropped out" in the name of interactivity. These items are, of course, rendered when navigation ceases. The amount of drop-out depends on several factors including: hardware (in particular graphics card and driver performance), as well as the size of the NavisWorks navigation window and the size of the model. If you wish to reduce drop-out during navigation, you have the option to reduce frame rate and, therefore, trade it off against drop-out.
When working with truely large "supermodels" in NavisWorks, you will require a sufficient amount of RAM to load and review the data. NavisWorks employs JetStream technology which optimizes the usage of the available RAM. Before running out of memory, NavisWorks will page unnecesary data to the hard disk, freeing up space for loading to continue. JetStream technology also enables the user to commence navigating the supermodel, before it has completely loaded into memory.
