   Help with AMD GPU PerfStudio 2.2
  I recently downloaded AMD GPU PerfStudio 2.2 and I want to be able to find the performance for a certain portion of my code.  However when I use the program I can't narrow down which draw call is the one I want to analyze.  I tried adding PIX begin and end calls, but these don't work in this program.  I was wondering if anybody knows how to do what I want, or if there are any tutorials online on how to use this product.  I checked AMD's website, but their tutorial is nothing more than a super simple introduction from what I can see.
