Vista - How do you intentionally LOWER the framerate?

If you are animating something that's inherently very slow-moving, such
as the minute and hour hand on an analog clock, how can you
intentionally make it update every 10 seconds or so instead of 60 times
a second? I just want to limit the drain on my processor! Here's an
example XAML DoubleAnimation element:

.... in a TransformGroup...
<RotateTransform x:Name="MinuteHandTransform" Angle="0" />

.... in a Storyboard ...
<DoubleAnimation
Storyboard.TargetName="MinuteHandTransform"
Storyboard.TargetProperty="Angle"
From="0" To="360" Duration="1:00:00" RepeatBehavior="Forever" />


I find no "Framerate" property on a Storyboard, Transform, or
Animation. Flash can set Framerate. Aren't we doing lots of similar
things as to what Flash can do? Wouldn't it be nice to limit the CPU
cycles spent on some parts of an animation so other parts can get more
emphasis?

Apparently, there is a StoryBoard.DesiredFrameRate property since Beta2
(May CTP).

Yes, DesiredFrameRate is the way to go. This property can be assigned to
any root timelines (in XAML, the parent Storyboard).

Laurent,

Sure enough, that did the trick! My processor utilization went from
around 60% down to an average 6.5%. Wonderful for anyone doing widget
development for the Sidebar.

Thanks again.

Btw, there's an example located at
