title: Slow WPF performance on GMA 500 integrated graphics
body: <p>My team is developing WPF applications to be deployed on an Intel Atom Z530 netbook hardware platform.  The Intel Atom Z530 comes with Intel GMA 500 integrated graphics, which has a PowerVR SGX 535 GPU core.  The PowerVR SGX 535 GPU core is the exact graphics core used in Apple's A4 chip set for the iPad.</p>
  
  <p>My question:
  Why is WPF so slow with PowerVR SGX 535 graphics?</p>
  
  <p>We actually turn hardware acceleration off for our WPF application to get better performance (screen to screen transitions, dialog transitions, 2D graphics interaction).  The iPad technology stack is able to achieve much better UI performance with the same hardware graphics core.</p>
  
  <p>Thank you for any insights!</p>
