Wow...another game that the 360 get the superior versions of. Looks like Rockstar got really lazy with this game and did a sub-HD port for the PS3. I find it baffling that many of the gamer forums have the PS3 fanboys trashing Alan Wake that was in development for 5 years, yet cannot get 720p out of the game despite the great visuals.

"Red Dead Redemption sports the same sub-HD resolution as its predecessor, Grand Theft Auto 4, on the PlayStation 3.
The lower resolution results in a slightly less sharp image compared to its Xbox 360 brother, it's been claimed.
The Xbox 360 version of Red Dead Redemption has been confirmed to be 720p with 2x anti-aliasing, whereas the PlayStation 3 version has been pared down to approximately 640p. That's a 20 per cent lower rendering resolution.
Veteran Beyond 3D technical forum member Al_Strong today confirmed the PS3 game's vertical resolution to be 640 pixel's high, but struggled to pin down its horizontal resolution.
Infamous pixel-counter Quaz51 (he broke Halo 3's sub-HD resolution) confirmed this analysis, adding that he believes that Redemption's horizontal resolution is the same as Grand Theft Auto 4's. This puts the PS3 version of Red Dead Redemption at 640x1152; the equivalent of 644p.
That's not to say that the PS3 version of the game doesn't enjoy the same graphical upgrades to Rockstar's GTA4 engine as the Xbox 360 game. No matter the platform, it's still one of the best games of the year, so don't go on a rage campaign just yet.
Moreover, since we've yet to have official confirmation from Rockstar, it's just a rumour for now, and more importantly - who cares?"
~~The Lens of Truth also does a pic comparison to show how the 360 trumps the PS3 port. I've been playing the PS3 for a couple days now and it still looks really good to the eyes, but these pics really show the differences.
