That is not true at all. The PS3 cannot upscale games so forcing it will only make things look worst on the ps3
Forcing on the PS3 just makes it actually lower itself from 720P because the game is not made for 1080p
the fact that it says it in the back means nothing since that is just a marketing ploy to make it more then what it is
Only the xbox can upscale properly to 1080p even though is not really true 1080p either. It is just an upscale version
Is like putting on cologne without taking a shower...You are just masking things and making it worst
make sure all settings are checked and let the game decide the best resolution
