Matt and I tested many cross platform games yesterday. So this feature on 1UP is no surprise to me.
I got even more cross platform titles today. The biggest difference is with Ridge Racer 6 and Ridge Racer 7, although this is to be expected, as it is actually a different game, not just a port to a different platform.
Suffice it to say that every game that is on the 360 and PS3 are the same. They are even output in 720p on the PS3, so the resolution isn't even different.
Take note with the video and screen grabs from 1UP the gamma of the PS3 versions of the games. Every single comparison shows lighter gamma on the PS3.
Matt and I noticed this as well. But we just chalked it up to using HDMI. But it seems we are not the only ones, as these screens and video show the PS3 to be lighter.
Sadly, in NBA 2K7 and Madden NFL 07, this equates to a "foggy" video. My Samsung HDTV has a great feature to fix this, but it should not have to.
Since 1UP captures are so light (too light if you ask me) I will contact Sony and the other developers to inquire further on this.
