    Hi all,

    i'm new to this forum - so i am not sure my question is placed right here.
    Anyway - here's the story and the question:

    I am developing a map display software in JAVA including a JNI layer to openGL.
    As you know the X51v supports openGl (common lite profile) by hardware (Intel G2700). For performance measures i wrote a little benchmark which displays ~2000 lines rotating over 3 axes.

    When using Intels hw support library (libGLES_CL.dll) i get ~6-10 FPS.
    Thats not very much.

    Now the question:
    When using the Vincent OpenGL_ES library - which is an open source implementation of OenGL_ES and is a software implementation only - i get ~12-16 FPS.

    Has anyone an Idea of an explanation to that behaviour ?

    Regards

      Well, of course, Vincent rocks... ;-)

      Seriously, either the hardware is not optimized for lines, or the driver cannot make use of it. Have you contacted Imagination Technologies to see if they can help you?

      Cheers,
      HM

      No - not yet, but I'll try.
      Its hard to find the real responsible manufacturer.
