title: AMD 64 bit Dual Core Optimization
body: <p>We have a graphics intensive application that seems to be experiencing problems on AMD 64 bit Dual Core platforms that are not apparent on Intel platforms.</p>
  
  <p>Running the application causes the CPU to run at 100%, in particular when using code for shadows and lighting (Open GL).</p>
  
  <p>Does anyone know of specific issues with AMD processors that could cause this or know where to track down the problem, and/or ways to optimize the code base to avoid these issues?</p>
  
  <p><em>note, the application generally works well on mid range hardware, my dev machine has an nvidia gtx260 card in, so lack of power should not be an issue</em></p>
