Clearly though when the gamepad is just generating minor map screens with minimal colours it will not require much processing. Unless we get wii u games that have full on action graphics being generated on both tv and gamepad simultanously I don't think we have to add both resolutions together. |
The compression part has nothing to do with what you said, it's just to mirror TV image to Gamepad. When you're rendering two different things, it's using more processing power, it doesn't matter if it's just a 2D map or something more complex, performance is being taken away from the main screen to render the second one.
