I don't think it would be using this system, as the viewpoint can be aimed in a totally different direction to the main screen, so it's probably simpler just to render a different camera view all the time.

It's essentially the equivalent of running in 2-player splitscreen at 900p/60fps, all the time. That takes a significant toll on the rendering budget of a system of Wii U's caliber. 

900p is 1,440,000 pixels per frame, combining the 480p and 720p native images only gives you a 1,331,520 pixel count, so still a distance away from 900p level, but as I said many frames will be using just a downsized fraction of what's being rendered on the main screen.

The cockpit is always using a portion of what's seen on the main screen, so it's not a unique image from any of the footage shown so far and I've seen all of the demos shown so far, the cockpit is fixed, it's not mobile in any of the vehicles in the game.

TBH this kind of thing isn't hard to do with that level of hardware, it's substantially more efficient than PS3 and 360 tech, plus the CPU isn't some in-order device that has to wait for each core to complete it's tasks until the next one can move on to the next one. The level of visuals aren't that demanding even for Wii U caliber hardware.

AMD GPU have been able to break up rendering targets and display them across multiple screens for a while now, this isn't anything that demanding really.

There have been many instances in the gameplay we've seen where the Gamepad view is facing at almost a 90 degree angle to the view on the main screen, showing none of the same geometry and assets, requiring completely separately rendered perspective.

Since the developers cannot control when the player will be doing this, it's likely that the Gamepad is never just a downsized view culled from the main screen.

As for the combined pixel count, it falls a little short of 900p, but it's a lot closer to 900p than to 720p.
