Radeon Shaders Broken.

[NaN]

Well, the frame buffer object check looks like this:

Code:

    else if (!GLEW_ARB_framebuffer_object)
    {
        info_output << "Your video card doesn't support framebuffer objects.  Disabling shaders." << endl;
        DisableShaders(shaderpath, error_output);
    }

Maybe a driver issue? GLEW says:

Experimental Drivers

GLEW obtains information on the supported extensions from the graphics driver. Experimental or pre-release drivers, however, might not report every available extension through the standard mechanism, in which case GLEW will report it unsupported. To circumvent this situation, the glewExperimental global switch can be turned on by setting it to GL_TRUE before calling glewInit(), which ensures that all extensions with valid entry points will be exposed.

Could you try "glewExperimental = true;" in graphics.cpp line 159 before glewInit() and report if it works?
