FrameTiming class not working?

Not sure what I’m doing wrong or this is a bug, but the FrameTiming class does not seem to work, because it is returning 0 for both cpu and gpu frame time.

FrameTiming ft = new FrameTiming()
Update(){
     print(ft.cpuFrameTime); //returns 0
     print(ft.gpuFrameTime); //returns 0
}

The documentation doesn’t really say much on how to get it to work.
Any idea on why it’s not working, or what I’m doing wrong?

Did you ever get to the bottom of this? I also get 0 returned.
