Set FPS Windows 8

Is it possible to change the frame rate for the windows 8 version?

pDirector->setAnimationInterval(1.0/30) does not seem to do anything.

When I look at the implementation of setAnimationInterval in CCApplication_win8_metro.cpp it says:

void CCApplication::setAnimationInterval(double interval)
{
// app need do nothing on metro. frame control in run.
}

What “run” is this referring to? I see CCFrameworkView::Run() but there is nothing about frame rate in there.

I want to limit the frame rate because graphic performance is choppy.
