Try turning off Profiles in the style and set the Face Style to Monochrome. Does that make it orbit more smoothly?

Perhaps it is the import from revit, but your model could be the poster child for how not to create a model in sketchup.
It is mostly raw geometry that has been incorrectly tagged.
Every time you change the view, orbit the model, it has to decide what to do with over 700000 individual entities.
The model should be constructed of groups and components and they should be assigned tags. As it is at the moment for some reason most of the faces in you model have been assigned tags that are different to the edges of those faces, this road leads to madness.
