Where's the game tweaker in Vista Ultimate?

[Pipboy]

According to this old article and others on the web Microsoft was touting a
game tweaker for Vista Ultimate. I don't see any such feature in Vista
Ultimate. Where is it?

Windows Vista Ultimate

The best operating system ever offered for a personal PC, optimized for the
individual. Windows Vista Ultimate is a superset of both Vista Home Premium
and Vista Business, so it includes all of the features of both of those
product versions, plus adds *Game Performance Tweaker* with integrated
gaming experiences,

It was never a "final" feature.

I know the rating system is still there.

As for a game tweaker I haven't heard anything about that in quite some
time.
