title: Qt & OpenGL: how to render as frequent as possible?
body: <p>I'm porting over a OpenGL application from a win32 project to a Qt project.</p>
  
  <p>In the win32 project I simply had a mainloop that kept executing the next frame as soon as the previous was finished.</p>
  
  <p>In the tutorials I find about Qt and OpenGL, they're using timers to control the update of the scene. However, I'd like to render as many frames as frequent as possible - how to do that?</p>
