Specifies the highest subdivision level that the Wireframe display option will update on a model. Setting this number to a lower value aids in improving the interactive performance when working with complex models. For more information, see Change the model display.
Increases the interactive performance when tumbling dense models in the range of 4 million quads and higher). If you want your model to look as detailed as possible and are not concerned about performance, set Fast Render Scale to a value of 0.1. Higher values in the range of 1.0 - 2.0 allow the model to tumble much faster but fine detail appears when you zoom in very close.
Imported quad models undergo a pre-processing phase when loaded into the 3D View. A model with pre-processing will tumble much faster when its polygon count is dense (4-100 million polygons). Upper and lower face count limits can be specified. Pre-processed models will not preserve the original vertex IDs.
