    You're right, the spec requires it. The driver never complained before... :confused:

    Re: NVIDIA releases OpenGL 4.2 drivers

    Well, my program stopped working. I found out that the problem is in this call:

    glVertexAttribPointer(0, 2, GL_FLOAT, false, 24, (void*)0);//GL_INVALID_OPERATION
    And I checked to make sure I have...

    Isn't it obvious? They're adding the API for ray-tracing... :p

    Re: Shader Model 3.0 in OpenGl

    Shader Model (1.0, 2.0 or 3.0) is just D3D way of grouping certain capabilities any given card has. OpenGL doesn't work this way. You can access everything SM3.0 provides for D3D, in GLSL. You make...

    Re: NVIDIA Forceware 75.90 => OpenGL 2.0.0 & fbo

    But the spec says a color renderbuffer/texture is not needed. And I call glDrawBuffer(GL_NONE). I think this is probably a bug related with MTR (and I am working with a FX5700, so no MTR support).
