WPF DropShadowEffect performance issue, looking for replacement

My wpf application was running very slow. I was using the performance profiling tools for wpf from windows and noticed my hardware IRTs per frame where very high (100+). I read in the help that this is caused by some effects. After disabling some effects i found that this was the cause...

        <Border.Effect>
            <DropShadowEffect Direction="45" Color="#DDDDDD"/>
        </Border.Effect>

I was using this effect on all my drag and drop objects.

Now I'm looking for a similar effect that doesn't freeze the entire application. Is there any effect in .net 4.0 what I can use to achieve this?

Thank you very much

David

Using bitmap caching in on the usercontrol also fixed the problem. Unless scaling is very important you could use this...

<UserControl x:Class="myControl"
   CacheMode="BitmapCache"
 >
 <Grid>
 </Grid>
</UserControl>
