title: Choose OpenGL ES 1.1 or OpenGL ES 2.0?
body: <p>I'm going to start a new cross-plattform openGL project (primary for iPhone &amp; PC). So theres the main question: targeting for OpenGL ES 1.1 or OpenGL ES 2.0? Or both? So far I read Open GL ES 1.1 isnt really deprecated, isn't it?
  So what would speak for openGL ES 2.0? Programmable vertex- &amp; fragmentshader - Anything else? I heard about performance decrease with alpha blending or so - can that be true? I assume openGL ES 2.0 code should also run on PC - So is openGL ES 2.0 is really more future aware?</p>
  
  <p>The other developers out there are still coding for OpenGL ES 1.1 or 2.0? And why?
  I assume in case I choose openGL ES 2.0, there would be a lot of overhead for also backward compatibility with openGL ES 1.1. But there are a lot of iPhones out there without openGL ES 2.0 support - how should I accomplish this? Any experience out there?</p>
  
  <p>I found only this question: <a href="https://stackoverflow.com/questions/2274017/opengl-es-1-1-or-2-0-on-iphone">OpenGL ES 1.1 or 2.0 on iPhone</a> kind of relevant, but it isn't really deep about the implementation...
  So any advice is welcome! Thank you so much!</p>
