What this article implies is true.. Yet it's not true at all.
Bungie did say they maxed out the 360, .. I personally saw the video.. BUT that was using a half modified OLD Halo engine....Bungie maxed out Halo Reach using a older Halo engine they modified. They weren't lie-ing ... They maxed out the 360 with that engine..
Play Halo 4... And then ask: Does it appear Bungie really maxed out the 360 hardware back then in Halo Reach?? ... Nope !
343 industries made an entirely new game engine that further pushed the 360 beyond what Bungie's older modified engine could ever dream of!! The new engine pushes Halo 4 graphics beyond what Bungie could do..
So you post two links of different companies saying they maxed out the 360.. How can Bungie have maxed it out back in 2010 with Reach? Only to post another link that 343 maxed it out AGAIN with Halo 4..
All this further proves is the engines for these games can take the system further.. NEW Engines use different optimization to improve over previous engines... What might have maxed out the 360 four years ago would be outdated software today ..
