Reflection on rusted metal

[Bishop81]

Probably just easier for them to code it that way and then there's the whole 'PS3 limitations' thing which we've all heard a thousand times.

Or they can just turn off the reflection for the metal ...

They have done so for the stone flooring outside (when dry).

Also I doubt the PS3 has enough power to spare for the DX11 reflections, thus PS3 limitations should be a non-issue.
