title: WPF DropShadowEffect performance issue, looking for replacement
body: <p>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...</p>
  
  <pre><code>        &lt;Border.Effect&gt;
              &lt;DropShadowEffect Direction="45" Color="#DDDDDD"/&gt;
          &lt;/Border.Effect&gt;
  </code></pre>
  
  <p>I was using this effect on all my drag and drop objects. </p>
  
  <p>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?</p>
  
  <p>Thank you very much</p>
