the resolution you set in 'Settings' on you xbox will not change the way the game renders images. Like Halo3, it says 720p/1080 on the box, but some people found out that it actually runs at 1152x640 and scales to 720/1080.
Very few games run at 1080 native.
So what you see is an upscaled image, and that does not improve image quality one bit.
Try out the different resolutions - I find that 720 gives the sharpest image
I'll eat my avatar if Birds of Prey runs at 1080!!!
