There are only a few sections where the gains were at all significant. Rather than a divergent library they probably could've realized a few optimization patches and gotten the same benefit. The thing I don't understand though is why so many software companies to this day still try to do so much low-level memory management themselves, as if the OS was incapable of it. It's not just gaming software either: case in point, Firefox and its insane memory management that bloats to using hundreds of megabytes over time.
