    Another new standard to not be used or implemented in any meaningful way.

    It would be a special kind of fail to release ES4 when ES3 is practically nonexistent on user devices.

    Khronos, don't fuck it up, make it so ES3 devices will run ES4.

    Default look the example of dx11 and dx10

    look the example of dx11 and dx10 and dx10.1 almost no games with dx10 in the market

    Free memory access for everyone everywhere, hooray! The input validation is there for a good reason. In best case, you just hang the hardware and have to reset. More worse, the application gets access to regions it's not allowed.

    You mean DX10.1 right? IIRC it's because AMD was the first one to support it by a long shot, there where a few games that implemented it, even some that removed the capability because Nvidia paid them off as DX10.1 made the games run noticeably faster then DX10.

    I believe DX12 is likely going to have similar requirements to Mantle - that is, RadeonSI and up for AMD, and i think Fermi is the equivalent on the NVidia side. My guess is that GL5 will be have the same requirements as well. They can always create a GL4.5 version that provides the parts that will run on older cards, just like they provided GL3.3 when 4.0 came out.

    Newer hardware implements virtual memory, and the hardware provides validation to make sure your app doesn't get access to something it shouldn't be able to see. Crashes can happen, though.

    Virtual memory and command stream checking should take care of gross misbehavior.

    But you are of course free to stick with current APIs if you need current levels of validation. Like for every draw call for every drawn frame...

    Edit:
    @smitty3268 beat me to it

    Yes and No. Manufacturers can update drivers for older hardware to bring support for newer OpenGL/DirectX revisions but they may choose not to do so.

    In short, the old APIs were not designed to be efficient
    select VS epoll is a good example.
