    metrics for state change load

    how much opengl get loaded by wich state change?
    is there a place where something like a graph or a scheme has been made yet?

    i'd like to identify by a glance where a state change bottleneck can be.

    You can't tell: it depends on the hardware/driver in use.
    You can profile, but again... on different systems you can have much different results.

    As a general programming headline, it's always best to minimize state changes, and to group them in your code.

    yes, i know... i've also noticed different behaviours on different cards.

    in fact, i was thinking to make such a scheme for the pourpose of comparing opengl systems.

    mainly a personal research
