Today I run my game and was very surprised about mysterious window:

Console opened at 02:58:46 09-Dec-11
        GL_CLAMP_VERTEX_COLOR_ARB is clamped.
        GL_CLAMP_FRAGMENT_COLOR_ARB is clamped.
        There are 0 constants bound by this program.
        Texture 0 uses an 32 bit floating point format.
        Texture 0 is bound to texture target GL_TEXTURE_2D.

If you are wondering what is it, it seems that recent NVidia drivers added this feature if you enable debug flag in your OpenGL 3+ context. Also, debug output quality seems to be improving:

OpenGL message 131218: Program/shader state performance warning: Fragment Shader is going to be recompiled because the shader key based on GL state mismatches. [source: API] [type: performance] [severity: medium]

It's nowhere near DirectX debugging tools, but hey, that's still better than 4-color LED.
