    Only for OpenCL (and maybe for really, really, really old OpenGL versions).

    Holy crap, they finally leapfrogged Direct3D, minus a few bits they're still missing, but up a good number of bits Direct3D 11.1 is missing. Good show!

    Well, okay, the two Big New Features are ARB extensions and not guaranteed to be available on any particular GL4.4 implementation, which is annoying, but still, those features will not be possible until D3D12.

    OpenGL 1.2 has conformance tests

    I'm replying for "maybe".

    It was interensting that OpenGL ES had conformance tests but (modern) OpenGL didn't. Now OpenGL finally gets one.

    Are you talking about GL_ARB_bindless_texture and GL_ARB_sparse_texture, or had you something else in mind? (And would you mind sharing your thoughts on the new extensions for us non-programmers?)
    I think D3D11.2 has sort of GL_ARB_sparse_texture (OpenGL had "only" GL_AMD_sparse_texture since 2011), but afaik D3D has still nothing like GL_ARB_bindless_texture (or former Nvidia's GL_NV_bindless_texture).
    Somebody knows why still no Direct State Acess?
    And what are your wishes for OpenGL 5/next?
    Core Profile only (cleaner and more efficient driver) with DSA?
    Edit: And ASTC in core profile (which would mean all next hardware would have hardware support)

    Didn't you write the exact same thing in the last OpenGL article. Are you a spam bot?

    When starting development on the next generation of GPUs manufacturers have to try an look years ahead in time. GPUs don't implement the bare minimum for any one given API. For OpenGL they often have costume extensions that gets included in later GL versions. Some times a GL version (3.3) is so superficial that any hardware supporting the previous version should be capable of handling the new one. Some features can be implemented in software with out to much of a penalty. These reasons combine to allow some hardware to support newer APIs then what was available when they where connived. That being said yes the hardware does dictate what version of OpenGL it can handle, the text on the box just isn't the final word. The Nvidia driver also supports multiple generations of GPUs and though the driver may be capable of the latest GL version (this doesn't mean that it has a software implementation) it won't be necessarily exposed for every supported GPU.

    Something changed since the last time?
