Additional content with variable fidelity

Technologies are disclosed herein for displaying application content and additional content, such as advertisements, notifications, and other additional content. A first version of additional content may be received by a client device, for example, when the client device is connected to a network, and stored on the client device. The client device may determine if one or more conditions are satisfied for retrieving, over a network, a second version of the additional content. The second version may have a higher video fidelity than the first version. If the one or more conditions are satisfied, the client device may retrieve the second version and display the second version of the additional content. If the one or more conditions are not satisfied, the first version may be retrieved and displayed. Subsequent to displaying the first or the second version of the additional content, the application content may be displayed.
