    Yeah that is a good idea , i was closed from it, it s not good to have new idea when you are close to release.
    the deferred sample is so well writen that it’s easy…but seems a bit slow…..

    kind regards

    Hi David,

    Sorry again for following up on old posts. When you say the DeferredRendering demo is slow, do you mean the OpenGL ES 2.0 or 3.0 version? OpenGL ES 2.0 is known to be much slower, as it has to repeatedly transform the scene as multiple render targets (MRTs) aren’t available.

    Thanks,
    Joe
