What
A quick-and-dirty hack for experimenting with a few undocumented SketchUp settings.
In particular, the following 2 settings were introduced in SketchUp 7.1 when a new rendering engine was implemented. When zooming/orbiting in the new engine, you may have noticed entities drop into wireframe mode and shadows turn off. The following 2 settings are supposed to give some control over when that happens.
Sketchup.full_detail_render_delay_min=1.0
Sketchup.full_detail_render_delay_max=5.0
As for the other settings in the dialog, they are not documented anywhere as far as I know; and may or may not be related to one another in any way.
