title: Performance difference between geometry shader and vertex shader
body: <p>Currently am rendering a model of around 1 million vertices. And inside vertex shader i am doing some complex computation for each vertex. Now i would like to increase the resolution of the model.
  I have two queries regarding this:</p>
  
  <ol>
  <li>Is it advisable to use geometry shader for increasing resolution to very large factors like 64 times?</li>
  <li>If i introduce a geometry shader i might need to move my computation from vertex shader to geometry shader. Whether doing an operation in verterx shader is same as doing it in geometry shader, in terms of performance. </li>
  </ol>
