By the way it looks very good at the 1280x720.
Pixel mapping is the best quality picture only if the source cannot provide more actual data.
For instance a DVD can never provide more actual information than the 854x480, so showing a higher resolution simply means somewhere along the line something has to guess what the extra dots should be made up of.
With a PC game you can actually provide more real data, thus nothing is guessing what should be there, but rather doing it's best to represent it with fewer dots.
So if you have 4 pixels of info and you show it using 16 pixels it doesn't matter. But if could somehow get 16 pixels of info, even if you only have 4 to show it all the better because you are essentially doing anti aliasing: rendering at a higher resolution and then showing at a lower one.
