Wow.
That is FAR greater than last generation's Red Dead Redemption differences... differences which could have been erased had Rockstar invested the effort and money to tap further into the SPUs on Cell to boost rendering at the time the game was released.
There's no such well of squandered potential on the XBO, just a significantly smaller GPU and far less effective memory bandwidth.
Top work Digital Foundry. It would have fascinated me no end had these differences been picked up by NeoGAF AFTER the full DF analysis hit. Actually, no it wouldn't.
Suddenly such differences shouldn't affect one's purchasing decision... pretty sure a 2fps advantage and a few extra blades of grass made the choice crystal clear last generation. Never mind the crushed blacks and compressed audio.
I'd REALLY love to see Digital Foundry's list of shareholders.
I know I'm coming off caffeine high, and my reading comprehension may be spotty....but what was your point?
