    PEP 3156, a new "asyncio" module, a new framework for asynchronous I/O

The full "What's New" document lists all major changes.

The Khronos Group has announced the immediate release of the OpenGL ES 3.1 specification, bringing significant functionality enhancements to the industry-leading, royalty-free 3D graphics API that is used on nearly all of the world’s mobile devices. OpenGL ES 3.1 will provide the most desired features of desktop OpenGL 4.4 in a form suitable for mobile devices.

XP32 / XP64 only - probably NVIDIA forgot the same security fix as they did last time

This 335.28 Game Ready Certified driver ensures you’ll have the best possible gaming experience for Titanfall.

        Enhanced GPU clock offset options for GeForce GTX 750Ti / GTX 750
    SLI Technology
        Diablo III – updated DX9 profile
        Bound by Flame – updated profile
        DOTA 2 – updated profile
        Need for Speed Rivals – updated DX11 profile
        Watch Dogs – updated profile

P.S: GpuCapsViewer reports false video RAM size under XP32
(only in the GUI, in database it appears correct)

NVIDIA overhauled their developer website, everything not CUDA SDK related is now available here:

The sample demonstrates shallow water solver implemented with the OpenCL™ technology. The Shallow Water sample relies on flux splitting method for solving the approximated Navier-Stokes equations. The algorithm operates on 2D maps of velocity and height, calculates updated maps for the next time step. The updated maps are rendered with pixel and vertex shaders (Microsoft DirectX* 10).

CUDA 6 introduces Unified Memory, which dramatically simplifies memory management for GPU computing. Now you can focus on writing parallel kernels when porting code to the GPU, and memory management becomes an optimization.

The CUDA 6 Release Candidate is now publicly available. In today’s CUDACast, I will show you some simple examples showing how easy it is to accelerate code on the GPU using Unified Memory in CUDA 6, and how powerful Unified Memory is for sharing C++ data structures between host and device code.

3D-Tech News Around The Web / AMD releases Chrome browser with WebCL
« on: March 15, 2014, 08:38:49 AM »
Chrome web Browser with WebCL™ now Available for Download
WebCL™ 1.0, soon to be published by the Khronos group, is a JavaScript API providing access to OpenCL™ acceleration, a sibling to the now quite popular WebGL™ API. AMD has been working on implementing WebCL™ inside a Chrome browser, enabling web programmer access to compute acceleration, including interop between WebCL™ and WebGL™.

It seems to be incompatible with NOKIA's WebCL?

ASUS GPUTweak 2.5.7 for WinXP32/64, Win7 32/64, Win8 32/64, Win8.1 32/64

No changelog available, but it contains ROMs for unreleased GPUs.
"LN2" = liquid nitrogen or marketing goof?


edit: here is a PR that explains it
Meet Your Matrix! (Pick: R9 290X or GTX 780 Ti)
"LN2 Mode / STD Mode Jumper Switch: Unleash the maximum GPU power."

Quote from: Manuel Guzman
I verified with our software team and indeed CSAA has been removed from Maxwell GPUs. Any mixed GPU systems that have both a Maxwell and an older NVIDIA GPU (i.e. Kepler) will also not display CSAA modes.

3D-Tech News Around The Web / Blender - Fibonacci fractal
« on: March 14, 2014, 07:48:50 PM »
It’s fractal time again! Reynante M. Martinez shared this Fibonacci fractal and also offers the .blend file for download.

Reynante writes:

    I was just able to finish this piece that’s been lurking in my space for quite awhile now. During the past weekend (can’t remember which one), I had the pleasure of creating a procedurally- inspired (sort of) Blender piece, with great influence from nature and mathematics.

    Attached here is the result of that experiment.

    The .blend file is also available, giving the community a chance to tinker with it as well and would love to see what they can come up with using the technique illustrated in the file.

    Fibonacci .blend and Hi-res image download

FYI: This formula is also "used" by the Romanesco broccoli (sic!)

3D-Tech News Around The Web / (Android) YEBIS OpenGL ES 3.0 Tech Demo
« on: March 13, 2014, 06:26:32 PM »
This is a technical demo previewing the capabilities of YEBIS 2 in OpenGL ES 3.0 (Android 4.3 and later).
YEBIS 2 is a post process library that enhances the realism and the beauty of rendered images in real-time.
Our previously released MOBILE GPUMARK application used only the OpenGL ES 2.0 feature set. With the new features provided in OpenGL ES 3.0, we can now deliver a higher level of detail and realism that was not possible with OpenGL ES 2.0.
The level of quality we once could only achieve on desktop machines can now be realized on Mobile devices. Try it and get a feel of the most cutting edge graphics on smartphones.
For more information about YEBIS 2, please check out our website:

Note: Please check our end-user license agreement before using this application

Note: This application has not yet been tested on all available GLES 3.0 devices. If you encounter any problems with it, we would appreciate your feedback via email.

What I am about to present here, may be one of the most important features in unbiased rendering ever. :-) Not kidding, probably.

This feature enters in the field of cheating, but the negative impact in the quality and purity of the render is often 0, while the benefit of removing fireflies entirely is probably the long lasting dream of every unbiased render engine user.

In most practical uses, the following is true:

With this feature, you can get rid of most (often ALL) of the fireflies in your render without (generally) affecting the render or losing visual components.
