    GeForce7900 Problem

    I've been doing some relatively simple programming and my GL apps are running very slow. I've run them on slower GPUs and CPUs and it runs faster on those. Any ideas if theres something wrong with the driver for the 7900?

    glGetString with GL_VENDOR, GL_RENDERER, GL_VERSION ? To be sure you have correct Nvidia drivers, and not software implementation from Microsoft.

    Can you be more precise about "some relatively simple programming" ?
    Maybe you force AA / aniso in display control panel ? Is it larger resolution ?

    All I'm doing is rendering 500 quads and it runs slower on my 2.4Ghz Core 2 Duo with a 7900 than it does on my laptop which is 1,7ghz single core and an old mobile ati card. The resolution is only 640x480 right now
