WebI primarily work with 2D graphics, and from what I can tell, they both seem to function the exact same way with no appreciable difference otherwise, save that the scissor test is more annoying to set up, because you have to create a new RasterizerState object to enable it. WebOne example of this is when an OpenGL-based composite manager is moving and repainting a window and the X server is trying to update the window as it moves, which are both CPU-intensive operations. You can use the __GL_YIELD environment variable to work around these scheduling problems.
