Hi Jeff Machamer,
Yes, there's a difference between restoring an maximized item and maximizing an minimized item. In the first case all your RadTileViewItems change their state and their content (largeContent -> content and smallContent -> content), but in the second only the previously maximized item and the newly maximized one change their content(largeContent->smallContent and smallContent->largeContent). So in the first case if you have 10 RadTileViewItems and all of them have some heavy control inside their restored content (like a chart or a gridview) when you restore the maximized item you'll have to create not 2 (like in the second case) but 10 grids or charts and that's where the delay comes from. You can try to remove the transition effects from the RadFluidContentControls and the animations from the RadTileView and see if this helps with the performance:
You can also disable the restoring of the maximized item by setting the MaximizeMode property of the RadTileView to "One".
If you need further assistance feel free to ask.
