title: cocos2dx error: opengl version too old
body: <p>I've upgraded my windows from 7 to 8 and I've started to compile cocos2dx but there is an error while the cmd is opening : </p>
  
  <pre><code>Your OpenGl Version is 1.1.0, but Cocos2d-x requires OpenGl 1.5 or higher on Windows. Please upgrade the driver of your video card
  </code></pre>
  
  <p>But cocos2dx was running well before upgrade!
  could u tell me what is the problem and what should I do?
  I'm using visual studio 2010.</p>
