3D-Tech News Around The Web / NVIDIA Drivers 340.17 for Linux, Solaris and FreeBSD
« Last post by Stefan on June 09, 2014, 03:27:33 PM »
    FreeBSD Display Driver – x64
    FreeBSD Display Driver – x86
    Solaris Display Driver – x64/x86
    Linux Display Driver - x86
    Linux 32-bit ARM Display Driver
    Linux x64 (AMD64/EM64T) Display Driver

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:

 Fixed an X driver bug that caused gamma ramp updates of the green channel at depth 15, on some recent GPUs, to be ignored.
GpuTest / Re: GpuTest 0.7.0
« Last post by Chris on June 09, 2014, 02:05:54 PM »
Not sure is this is a 0.7 issue but I get this whenever I try to run either from the GUI or from the CL

./GpuTest: 3: Syntax error: word unexpected (expecting ")")

Any ideas?

I updated the demo with light spheres technique which drastically improved the framerate. With previous naive technique, the demo ran at around 50FPS for 200 lights, now the demo runs at 300FPS!

I also added the speculars on the torus and sphere:

The speculars have an impact on the FPS ;)

A new dev version of GLSL Hacker is ready for Windows 64-bit.

You can download it from this page:

Version - 2014.06.04
! updated the OpenGL context creation under Windows and Linux for when
  the required major version is 2.
+ added create_ex_v3() to gh_render_target lib.
+ added uniform_camera_matrices() and uniform_object_matrix() to gh_gpu_program lib.

GLSL Hacker adds new functions used in my deferred rendering tests.
3D-Tech News Around The Web / AMD EDID Utility 1.0
« Last post by Stefan 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.
Gigabyte Unveils SuperOverclock VRM Boards for Graphics Cards

Gigabyte showed us its new range of auxiliary VRM boards for graphics cards, designed for professional overclockers. The board has to be manually soldered onto your graphics card, it supplements your card's GPU power domains. The card features a high-current power stage, which draws power from five 8-pin PCIe power connectors.

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
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
