Hi,

I guess this is a very simple question on the Channel Load and PipeLoad.

The man pages say that

pfGetChanLoad will return the last computed load for chan. The load
     value is defined as time * frameRate / frac.

AND ...

     pfGetPipeLoad returns the current instantaneous load (ratio of time
     required to process a frame and the time allotted for that frame's
     processing) for the pipe.

For a Pipe with single channel, frac = 1.0f; both should be the same if
I understood these correctly.

What does it mean when ChanLoad is 0.6314 and PipeLoad is 0.67150 and
values like that ? Seems to have a perfect ratio, if the load values are
close to 1.0f.

BUT,

I notice that the my simple app drops frame-rate when the PipeLoad goes
above 0.75-0.8. ????

Thanks in advance
