In bigges scenes i even display objects only as wireframe or even wireframe boxes - a lot faster. I sometimes found files very slow with imported objects in it. Objects with a lot of not connected polygons. Like trees or a splash coming from Cinema. "Only" 200.000 polygons for example, but the file becomes very very slow - and very very big. And it has nothing to do with the fact that i am on a Mac!
