BioWare is on the record in stating that the PS3 version of Mass Effect 2 has enhanced visuals.
"One of the first things you're going to see is improved graphics," game producer Jesse Houston said during a recent BioWare podcast. "We actually created the engine for Mass Effect 3 and used that to make Mass Effect 2 PS3. So we took the content, the story and all of the other assets that made up Mass Effect 2 and we put it into the Mass Effect 3 engine."
It stands to reason that BioWare would want to make adjustments to the core engine for what is now a cross-platform project: this is, after all, an extensively retooled Unreal Engine 3. However, direct visual comparisons with the same scenes on the existing Xbox 360 version of Mass Effect 2 suggest that not all of the changes are not for the better. There's a curious mixture of improvements, downgrades and swapped out effects.
