title: How to tell the graphic card memory usage?
body: <p>My application seems to be slow, but in terms of CPU and RAM, it seems that it is OK. So, I want to know how much memory of the graphic card I am using. I've seen some questions about this on SO, but they talk about Linux or NVidia. I would like to have this information for ATI cards on Windows.</p>
  
  <p>Thanks.</p>
