I currently have following code:

int pixelFormatIndex = 0;
    int pixelCount = 0;


    std::vector<int> pixAttribs;
    
    // specify the important attributes for the pixelformat used by OpenGL
    int standardAttribs[] = {
        WGL_SUPPORT_OPENGL_ARB, 1, // Must support OGL rendering
        WGL_DRAW_TO_WINDOW_ARB, 1, // pf that can run a window
        WGL_ACCELERATION_ARB, WGL_FULL_ACCELERATION_ARB, // must be HW accelerated
        WGL_RED_BITS_ARB, 8,
        WGL_GREEN_BITS_ARB, 8,
        WGL_BLUE_BITS_ARB, 8,
        WGL_ALPHA_BITS_ARB, 8,
        WGL_DEPTH_BITS_ARB, 16, // 16 bits of depth precision for window
        //WGL_STENCIL_BITS_ARB, 8,
        WGL_DOUBLE_BUFFER_ARB, GL_TRUE, // Double buffered context
        WGL_PIXEL_TYPE_ARB, WGL_TYPE_RGBA_ARB, // pf should be RGBA type
        0}; // NULL termination
    
    pixAttribs.insert(pixAttribs.begin(),standardAttribs,standardAttribs+(sizeof(standardAttribs)/sizeof(int)));
    
    // specify multisampling mode if it has been set
    if(mMSMode != SLIMGF_MULTISAMPLING_OFF) {
        pixAttribs.push_back(WGL_SAMPLES_ARB);
        pixAttribs.push_back(mMSMode);
    }


    // OpenGL will return the best format for the pixel attributes defined above
    BOOL result = wglChoosePixelFormatARB(mDeviceContext, pixAttribs.data(), NULL, 1, &pixelFormatIndex, (UINT*)&pixelCount);
    ASSERT(result != false, "wglChoosePixelFormatARB() failed");
 

The problem is when im using WGL_ACCELERATION_ARB, WGL_FULL_ACCELERATION_ARB my screen just stays black and when im not using it my device created is Version 1.1.

I listed two picks with and without the hw support flag (info obtained by wglGetPixelFormatAttribivARB())

[attachment=13576:nohwacc.png]

The format with hardware support got a 24bit depth buffer and from some trying I thought that may have something to do with the problem allthough i dont know why.

Im using the newest version of GLEW that is succesfully intialized before.

My GPU is a GTX680.

I currently render with following test code:

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);


    glBegin(GL_TRIANGLES);


    glColor3f( 255, 0, 0 ); // red
    glVertex3f(-1.0f, -0.5f, -5.0f);
    
    glVertex3f(1.0f, -0.5f, -5.0f);
    glVertex3f(0.0f, 0.5f, -5.0f);
    
    glEnd();
 

I already thought about OpenGL4.2 causing problems with render this old way?

Thanks in advance

I already thought about OpenGL4.2 causing problems with render this old way?

Are you saying that you're creating a version 4.2 rendering context and using immediate mode rendering? Immediate mode was completely removed from the API in version 3.3, and from version 3.0 if you use a core profile context. You are required to use shaders and vertex arrays to do the rendering now.

Thank you very much. I just started with OpenGL but wanted to port my old Windows System class first, I used with my DX9 framework before getting into OpenGL itself so i did not know about that. It seems that immediate mode rendering stopped working with 3.2. Creating a render context >= 3.2 causes my screen to stay black.

Immediate rendering was thrown out at 3.0, 2.1 should be the last version where you can do it. You can always just query a non-core context and do whatever you want.
