    Question Performance of GLSL?

    Hi all. I'm trying to use shaders to perform image rotation in my application.
    I followed the tutorial for rendering a simple model using shaders. For this simple application itself it takes 50% of my processor usage.
    My PC Spec:1GB Nvidia 210 Graphic Card,2GB RAM,3 Ghz Processor. I've updated my graphics drivers & tested it too.

    Code Reference:
    http://www.opengl.org/sdk/docs/tutor...rs/loading.php

    Actually it questions the base itself. Why it is consuming this much CPU load for rendering a simple model? If we are using GPU for this rendering process then what takes this much of CPU load?

    forgive me if i did anything wrong. But please help me to understand about this shaders & help me to tune my Application performance.

    Well, you probably render thousands of frames per seconds. In that case it is quite possible.
