Apple Adds OpenGL 4 Support in OS X 10.9 Mavericks!



Mac OS X 10.9 Mavericks


Yeah, it’s official, Apple has finally updated the OpenGL support in its new version of OS X. OS X 10.9 codenamed Mavericks will be available with… OpenGL 4.1 core profile!

Okay, OS X is still in late compared to Windows / Linux (OpenGL 4.3) but it’s a great news!

Here is the interesting part of OS X 10.9 release notes:

OpenGL 4 in OS X 10.9

Mac OS X 10.9 Mavericks



Can’t wait to test the tessellation demo of GpuTest with OS X 10.9…

GpuTest 0.4.0 with OpenGL 4 test for Mac OS X
GpuTest for Max OS X with OpenGL 4 ready test

    Yeah, it should be 4.0.

    Is it 3.2 or 4.1 or
    3.2 vs 3.3 vs 4.0 vs …

    I suppose Apple will add something like kCGLOGLPVersion_4_1_Core and NSOpenGLProfileVersion4_1Core to the new OpenGL SDK.

    Nice!

    OpenGL 4.1 also means ARB_ES2_compatibility supported which means being able to use OpenGL ES2 code usable on Macs in addition to smartphones! Unified code base win!

    Any chance of posting the full extensions list? Hopefully they’ll be adding compute shader extensions support since it’s becoming increasingly popular for DX11 games.

  5. JeGX Post Author

    Compute shaders are part of the OpenGL 4.3 core so I don’t think Apple will add this support. But on some hardware like NVIDIA GPUs, maybe compute shaders will be available (like with the tessellation)!

    the flag/enum to create an opengl core context stayed the same (kCGLOGLPVersion_3_2_Core), so all programs already creating an opengl core context automatically use opengl 4.1 now.

    besides opencl support for intel gpus (yay), nvidia cards also support opencl 1.2 now (extension list below).

    The OpenCL 1.2 support on Nvidia cards, as well as HD4000 OpenCL support are both great news! Thanks a lot cmf!

    after some testing, I have to say that opencl support on the intel gpu is quite solid. the only thing that seems to be broken is retrieving compiled opencl program/kernel binaries (amd gpus on os x have the same issue). performance is about 1/3 of the gt 650m. and it’s supporting host unified memory (haven’t tested it yet, but the flag is set).

    also supported by both the intel and the nvidia gpu *drumroll*: printf :)

    unsupported by both: device partitioning and built-in kernels (does anybody support this?)

    apparently as an alternative to device partitioning, apple has added a new extension called “cl_APPLE_command_queue_select_compute_units”.
    info from cl_ext.h:
    /* Extension: clCreateCommandQueueWithPropertiesAPPLE
    * Create a command queue for the specified device. The properties array
    * specifies a list of command queue property names and their corresponding
    * values. Each property name is immediately followed by the corresponding
    * value. The list is terminated with 0.
    *
    * List of supported properties are:
    *
    * CL_QUEUE_PROPERTIES cl_command_queue_properties bitfield
    * ( CL_QUEUE_PROFILING_ENABLE,
    * CL_QUEUE_OUT_OF_ORDER_EXEC_MODE_ENABLE)
    *
    * CL_COMMAND_QUEUE_PRIORITY_APPLE cl_queue_properties_APPLE
    * ( CL_COMMAND_QUEUE_PRIORITY_DEFAULT_APPLE,
    * CL_COMMAND_QUEUE_PRIORITY_BACKGROUND_APPLE )
    *
    * These properties may only be used if the cl_APPLE_command_queue_priority is
    * supported by the device.
    *
    * CL_COMMAND_QUEUE_NUM_COMPUTE_UNITS_APPLE int (value can be 1 .. CL_DEVICE_MAX_COMPUTE_UNITS).
    *
    * This property may only be used if the
    * cl_APPLE_command_queue_select_compute_units extension is supported by the
    * device.

    I hope that Mavericks will signal a return of stereoscopic 3D support. It worked OK in 10.6, and it has been downhill since then.

    “it’s supporting host unified memory” IOSurface handles unified memory between OpenCL, OpenGL, GLKit, etc

  11. Sean McGuffee

    Where are the headers?
    ls -lrt /System/Library/Frameworks/OpenGL.framework/Headers
    ls: /System/Library/Frameworks/OpenGL.framework/Headers: No such file or directory

    Just bought a PNY quadro 4000 for Mac. Guess what…there are no drivers for Mavericks. Useless at this time. I guess I have to return the card or erase my hard drive and go back to Mountain Lion. Don’t download Mavericks until they have drivers for your video card.
