I have determined that the more graphics/pixels you put into an image it puts more strain on the console and processor so you can deffinately tell that Reach has far better graphics than Halo 3, especially the armour effects. This being evident of plenty of stuttering and slowing down of gameplay that i've noticed several times, I have an origional xbox 360 so maybe elite or slim console users won't see this. But it has been really bad. But Halo 3 and Halo: Reach are just as entertaining as eachother, but never as good as the first. Sorry bungie, keep tryin ^^
