According to Quaz51, the internet tech warrior that brought word of MGO's resolution-based shortcomings over the weekend, has posted here (post number 513) claiming that the PS3 version of GTA IV runs at 630p (1120x630) compared to the 360 version's 720p (1280x720).
This appears to mean that the 360 version has a whopping 24.5 percent extra resolution over the PS3 game.
Quaz51 still reckons the PS3 version looks better, however, due to superior processing effects.
We're reliably informed that the tech community has been kept guessing on the issue by the fact that Rockstar appears to have only ever released Xbox 360 screens of the game.
We'll be quite glad when this is all over in a few hours. Or next year.
