While you may be right, I'm hoping you're not. :shock:
To see the performance discrepancy, you need an HD set. I put my work-in-progress game here:

Set your display type to "4:3 standard", let the box reboot, and then launch the game. Run around the perimeter of the map to get a feel for how quickly it runs.
Now set your display to "HDTV 720p", reboot, and launch it again. You'll see how horrendous the gameplay difference is. It's because it stretches the X & Y axes by a factor of two, effectively drawing 4 times as much artwork as before. At 4:3, it's easy to imagine running around and facing off against an enemy. At 720p, it would be basically impossible.
Do a search for roImageCanvas in this forum for a couple threads that discuss the image canvas performance in depth. There are a number of things you can do to improve performance, but it's unlikely you'll ever get the same 480p performance at 720p.

Since a manual settings change provides what I need, it seems like this is a software issue, not hardware. If that's true, then maybe some of the Roku engineers will consider looking into a solution?
As you already noted, a manual settings change requires a reboot, so I'm not sure why you'd think it was software and not hardware... ?
