Turning off shadows

A couple of SolidWorks questions. I can’t seem to turn off the shadows, which just waste cpu cycles on student computers. I have shadows unchecked under scenes but  they still persist.

 

Out of the box SW replaces the feature manager with the mate properties and overlays the feature manager on the view. I prefer the feature manager to stay put and the mate properties to pop open and float.

 

I set all this up years ago for my old computer and don’t remember how!
