"Yerli went on to describe how the engine is being built to perform across platforms. "The CE3 runs currently at more or less the same quality bar. I say more or less because the engine still optimizes itself to power of the platforms' intrinsics. So the PS3 will run slightly better here, it'll look and feel probably the same, but the engine is diverting computation needs to power subsystems available to the PS3, and the 360 differently, and PC differently."
