Made various improvements and corrections to the information reported to GL applications via the KHR_debug and ARB_debug_output extensions.
 Fixed a bug that caused GLX applications which simultaneously create drawables on multiple X servers to crash when swapping buffers.
 Updated nvidia-settings to report all valid names for each target when querying target types, e.g. `nvidia-settings -q gpus`.
 Added support for controlling the availability of Fast Approximate Antialiasing (FXAA) on a per-application basis via the new __GL_ALLOW_FXAA_USAGE environment variable and the corresponding GLAllowFXAAUsage application profile key. See the README for details.
 Fixed a bug where indirect rendering could become corrupted on system configurations that disallow writing to executable memory.
 Updated the nvidia-settings Makefiles to allow nvidia-settings to be dynamically linked against the host system's libjansson. This option can be enabled by setting the NV_USE_BUNDLED_LIBJANSSON Makefile variable to 0. Please note that nvidia-settings requires libjansson version 2.2 or later.
 Added initial support for G-SYNC monitors. Additional details and system requirements can be found at:

3D-Tech News Around The Web / AMD EDID Utility 1.0
« on: June 03, 2014, 07:28:18 PM »
The AMD EDID Utility is a useful tool that can read the EDID information from connected display devices and save it to a text or binary file. EDID is a data structure provided by digital displays to describe its capabilities to a video source such as a Graphic Processing Unit (GPU). It thereby enables a personal computer to know what kinds of monitors are connected to it and thus the capabilities of the identified monitor.
In some cases incorrect display behavior can be caused by wrong data being stored in the EDID data structure. Using this utility, a user may save the EDID information so it can be used later by AMD or OEMs to emulate a particular display device, or to inspect display EDID content, which can be a helpful diagnostic tool.

OpenGL ES 3.0 Instanced Rendering By batch-rendering multiple versions of the same mesh, instanced rendering can help developers using OpenGL ES 3.0 and later dramatically improve performance and resource efficiency.

The sample compiled correctly with ARM V7 binaries, but then crashed with Adreno 320 (Nexus 4)
Judging from logcat the culprit might be GUIShaderOGL.ps
I have no idea though what to change.

If you are too lazy to compile and want to try on MALI 600 or Tegra K1, get the APK here

[New App] NVIDIA Posts An App For The FaceWorks Tegra K1 Demo, Despite A Complete Lack Of K1 Hardware

Now there's an app in the Play Store that lets you try FaceWorks on your own Tegra K1-powered Android device. Of course that's going to be a little tough, since at the moment there aren't any available at retail, so the app is incompatible with everything. The first Tegra K1 device to be announced was the Xiaomi Mipad, and the tablet is scheduled to go on sale in China (and only China) next month.

NVIDIA UN*X driver portal


    Added support for the following GPUs:
        GeForce GTX TITAN Z
        GeForce GT 740
        GeForce 830M
        GeForce 840M
        GeForce 845M
        GeForce GTX 850M
    Fixed a bug that caused X to crash when querying clock offsets for non-existent performance levels.
    Fixed a performance regression when running KDE with desktop effects using the OpenGL compositing backend.
    Fixed a bug that caused duplicate entries to appear in some dropdown menus in the "Application Profiles" page of nvidia-settings.
    Fixed a regression that could cause OpenGL rendering corruption on X screens with 30 bit per pixel color.
    Fixed a bug causing mode validation to fail for 4K resolutions over HDMI in certain situations.
    Added nvidia-settings command line controls for over- and under-clocking attributes.  Please see the nvidia-settings(1) manual page for more details.
    Fixed several cosmetic issues in the clock control user interface of nvidia-settings.
    Added support for the GLX_EXT_stereo_tree extension.  For more details, see the extension specification:
        http://www.opengl.org/registry/specs/EXT/glx_stereo_tree.txt
    Enabled support for using Unified Back Buffer (UBB) and 3D Stereo with the composite extension on Quadro cards.  Using stereo with a composite manager requires a stereo-aware composite manager.  Otherwise, only the left eye of stereo applications will be displayed.  See the GLX_EXT_stereo_tree extension specification for more details.
    Updated the display configuration page in nvidia-settings to uniquely identify DisplayPort 1.2 monitors by displaying the monitor GUIDs.
    Fixed a bug that could cause ECC settings to be displayed incorrectly in nvidia-settings when changing ECC settings on a multi-GPU system.
    Removed the "OnDemandVBlankInterrupts" X configuration option: this option has been enabled by default since version 177.68 of the NVIDIA Unix driver, and the documentation had not been updated to
    reflect the new default value.
    Fixed a bug that caused GPU errors when hotplugging daisy-chained DisplayPort 1.2 displays.
    Updated the color correction settings page in the nvidia-settings control panel to reflect gamma changes made by other RandR clients while the control panel was already running.
    Fixed a bug that prevented the use of multiple simultaneous X servers on UEFI systems.
    Updated the nvidia-settings source package to build libXNVCtrl when building nvidia-settings, instead of relying on a pre-built library.
    Added the ability to over- and under-clock certain GeForce GPUs in the GeForce GTX 400 series and later.  For GPUs that allow it, an offset can be applied to clock values in some clock domains of some performance levels.  This clock manipulation is done at the user's own risk.  See the README documentation of the "CoolBits" X configuration option for more details.
    Updated the minimum required version of GTK+ from 2.2 to 2.4 for nvidia-settings.
    Renamed the RandR output property _GUID to GUID now that it is an official property documented in randrproto.txt:
        http://cgit.freedesktop.org/xorg/proto/randrproto/commit/?id=19fc4c5a72eb9919d720ad66734029d9f8e313b1
    Reduced CPU utilization and GPU memory utilization of the NVIDIA EGL driver.
    Added support for the following EGL extensions:
        - EGL_EXT_buffer_age;
        - EGL_EXT_client_extensions;
        - EGL_EXT_platform_base;
        - EGL_EXT_platform_x11.
    Renamed the "Clone" setting of the "MetaModeOrientation" X configuration option to "SamePositionAs", to make clear that this setting applies to
    the position only, and not to the resolution of modes in the MetaMode.
    Added NV-CONTROL attribute NV_CTRL_VIDEO_ENCODER_UTILIZATION to query utilization percentage of the video encoder engine.
    Added support for the GLX_NV_delay_before_swap extension.  For more details, see the extension specification:
        http://www.opengl.org/registry/specs/NV/glx_delay_before_swap.txt
    Report correct buffer sizes for RGB GLX visuals, GLXFBConfigs, and EGLConfigs.  Previously, RGB10 and RGB8 formats were reported as having 32 bits, and RGB5 formats were reported as having 16 bits.  Now they are correctly reported as 30, 24, and 15 bit formats respectively as required by the GLX and EGL specifications.

Selecting a GPU for OpenCL on the Mac Pro (Late 2013)

The Mac Pro (Late 2013) includes dual AMD FirePro workstation-class GPUs that are ideal for compute intensive tasks. This document describes how to query the GPUs and select one or both for use by OpenCL.

The Mac Pro (Late 2013) is different from other Macs as only the primary GPU provides output for the display. The secondary GPU provides additional processing capability and can perform OpenCL and off-screen OpenGL tasks without affecting the responsiveness of the user interface.
