It took only two months for NVIDIA to pass all my OpenGL 4.2 samples successfully. This is pretty impressive! Congratulation to NVIDIA for their first official release of OpenGL 4.2 drivers.
We are still at a pretty early stage of OpenGL 4.2 life and I can't exclude missing out bugs but the OpenGL Samples Pack 4.2.1 is already doing a pretty large coverage of the OpenGL 4.2 API so that I don't expect too much surprizes.
Finally, a NVIDIA bonus on debug output: Following, a message I saw in my debug output while doing this status. I have been mostly working on AMD for the past month, I need to investigate more but this might be a great news!
131185: Buffer detailed info: Buffer object 3 (bound to GL_UNIFORM_BUFFER (2), and GL_UNIFORM_BUFFER_EXT, usage hint is GL_ENUM_88e8) will use SYSTEM HEAP memory as the source for buffer object operations.
Meanwhile, no new drivers on AMD side. Hence, the status remains the same than last month. Yes, AMD has released new drivers but no package with a more rescent OpenGL drivers.
- White: Unsupported or untested.
- Blue: The sample works but it doesn't follow the OpenGL specification.
- Green: The sample works following the OpenGL specification.
- Orange: The sample doesn't work correctly but a workaround is possible.
- Red: The sample does't work and I haven't found any workaround.
- Black: Really distubing problem!
These tests have been done on Seven 64 with the OpenGL Samples Pack 4.2.1.1.
