title: Performance of WebGL and OpenGL
body: <p>For the past month I've been messing with WebGL, and found that if I create and draw a large vertex buffer it causes low FPS. Does anyone know if it be the same if I used OpenGL with C++? </p>
  
  <p>Is that a bottleneck with the language used (JavaScript in the case of WebGL) or the GPU?</p>
  
  <p>WebGL <a href="http://alteredqualia.com/three/examples/webgl_cubes.html" rel="noreferrer">examples like this</a> show that you can draw 150,000 cubes using one buffer with good performance but anything more than this, I get FPS drops. Would that be the same with OpenGL, or would it be able to handle a larger buffer?</p>
  
  <p>Basically, I've got to make a decision to continue using WebGL and try to optimise by code or - if you tell me OpenGL would perform better and it's a language speed bottleneck, switch to C++ and use OpenGL.</p>
