Let me put this better. PS3 vs 360, On PS3 whenever you started a game, the system would flip through resolutions to see which resolution is used and compatible on the software. Software base upscalers would make the image flip back into 1080p on PS3 and your TV will notify you that you're in 1080p (most TV's so, but not all tell you). If the game only was programed at 720p, the PS3 would flip into 720p and the TV would have to upscale itself making images look slightly pixelated in alot of cases. On Xbox 360, the system starts in 1 resolution and stays in that one resolution whether you start a game, a app or or in the menu because it upscales at a hardware level, making things alot simpler. It's why alot of the time earlier on in the gen PS3 (Edit: Wrote PS4 before by accident lol) games had more pixelation compared to Xbox. Xbox's games had AA on software being upscaled at a hardware level making the game look alot more smooth while using less power to do so. Only a few cases Where PS3 beat it out like FFXIII etc. This is a good thing now.
