A Fast Style disables a style’s more taxing effects — that is, settings that require additional processing and slow down SketchUp as your model becomes more complex. If any of the following settings are enabled, then the style will lose its classification as a Fast Style and the badge will no longer appear.
Edge Styles
-Profiles
-Depth Cue
-Extension
-Endpoints
-Jitter
-Sketchy Edges
Face Styles
-X-Ray with Transparency: Medium
-X-Ray with Transparency: Nicer
-Transparency: Medium
-Transparency: Nicer
Note: Every face style, including X-Ray, with Transparency set to Medium or Nicer will lose the Fast Style classification. The one exception is the Wireframe face style, which remains a Fast Style with any Transparency setting.
