title: Can I increase performances using glscissor
body: <p>I'm working on a 2D game for android using OpenGL ES 1.1 and I would like to know if this idea is good/bad/useless.</p>
  
  <p>I have a screen divided in 3 sections, so I used scissors to avoid object overlapping from one view to the other.</p>
  
  <p>I roughly understand the low level implementation of scissor and since my draws take a big part of the computation, I'm looking for ideas to speed it up.</p>
  
  <p>My current idea is as follows:</p>
  
  <p>If I put a glscissor around each object before I draw it, would I increase the speed of my application.</p>
  
  <p>The idea is if I put a GLScissor, (center+/-sizetexture), then the OpenGL pipeline will have less tests to do (since it can discard 90~99% of the surface thanks to the glscissors.</p>
  
  <p>So to all opengl experts, is this good, bad or will have no impact ? And why?</p>
