    Re: 30.000 triangles

    I've done dysplay lists on Inmediate mode geometry and works at 20 FPS on a ATI 7000 and a geforce 2 MX, so that you have solved my problem. Thanks a lot.

    In cards without T&L i only get 1 or 2 FPS but the scene is heavy and it is normal (i think).

    Thanks a lot.

    Why are people suggesting vtune?
    VTune will only tell you where the CPU is spending time, not the GPU.
    If you're T&L bound, then all vtune will show is a hotspot at the drawelements call, or glvertex if you're using it. And that's it. But you already know that a tnt2 is going to spend a lot of time in drawelements because it's performing the transforms on the CPU, so it's not really told you anything you don't know already.
    Not really worth downloading for this particular case. (btw, www.grokster.com to see if someone will 'share' vtune with you).

    The guy was not using T&L. Thus, he'll likely be spending time in the GL driver for his card. Being told that's what you do will give a good indication of what to change.

    Note that a Radeon 7000 does NOT have T&L.
