Component maker Zotac is one of NVIDIA's closest partners and it has now announced the new ZOTAC GeForce GTX 460 3DP that offers something unique, name support for up to four monitors.

Full story here

Afaik Forceware only supports only 2 monitors per GPU. I wonder how this card internally works  ???

We have improved the support of the latest Intel Sandy Bridge processor in CPU-Z.
It does now display the processor name and logo, as well as the memory frequency and timings.

You can download the beta version at that address.

3D-Tech News Around The Web / TheaRender - interactive render beta
« on: September 22, 2010, 05:34:38 PM »
Our first goal with interactive render (IR) was the full integration of our OpenGL viewport. This way, IR can be used the same way with the same navigation controls. Besides the integration with the viewport, full integration with the rest of UI is implemented, so that almost every function of Thea works in co-operation with IR. This way, we can tweak settings, apply materials, etc. with IR keep working in the background.

The second goal, was the render method itself. We wanted a new mode that would be as fast as possible especially in initial updates. Although this can be parameterized to use TR1/TR2 unbiased methods, for IR we developed two "lighter" techniques; one progressive biased and a Monte Carlo unbiased.

In today's Dispatch, we transport you to the nexus where fantasy meets technology. And at the center of it all, you'll find Intel HD Graphics, our newest integrated graphics offering and the first to include the CPU and GPU in one package. Beam me up, Scottie!

•           When designing games, developing for both maximum gameplay and reduced power consumption can be a constant concern. In Star Trek* Online Goes Where No Game Has Gone Before, Jimb Esser, the lead graphics programmer for Cryptic, discusses the challenges faced in taking this beloved franchise into the world of MMO gaming, and why optimizing the game to run on processors equipped with Intel HD Graphics was an obvious choice.

•           The 2010 Intel® Core™ processor family with Intel HD Graphics provides new features that improve system performance and reduce power usage, especially in mobile systems. Now, both developing and running applications when on-the-go with your laptop can give you increased performance. Read how in the Intel® HD Graphics Dynamic Frequency Technology white paper.

- Added simple api to control dxprof behaviour from the target application

3D-Tech News Around The Web / Indigo Renderer 2.4 released
« on: September 22, 2010, 01:12:31 AM »
Indigo 2.4 is dramatically faster than Indigo 2.2, a result of numerous optimisations in the core rendering engine: vastly more efficient MLT, up to 2X faster instancing and motion blur in complex scenes, colour noise is completely eliminated, 4X faster blackbody illumination and many other substantial improvements.

Indigo shaders run 10-20X faster using Indigo 2.4 in 64 bit mode than Indigo 2.2 64 bit, a night-and-day performance difference for complex materials.

After 27 minutes the testscene still looked grainy  ???

In fact, today a new Gallium3D state tracker was pushed into Mesa and it's perhaps the most interesting state tracker for this open-source graphics driver architecture yet. It's a state tracker that exposes Microsoft's DirectX 10/11 API on Linux! And it's already working and can be hooked into Wine!

3D-Tech News Around The Web / Nvidia announces CUDA x86
« on: September 22, 2010, 01:06:20 AM »
The incoming PGI CUDA C compiler for x86 allows developers to optimize CUDA applications for x86 systems that don't include an Nvidia GPU

...application I developed for my diploma thesis "Realistic visualization of a character in a real-time application" with Unity including:

- Skin Shading (incl. a subsurface scattering approximation)
- Hair Shading (anisotropic specular, ...)
- Cloth Simulation
- Facial animation (incl. detailed dynamic normal maps)
- and much more... ;)

To download the application and for more information about this project, have a look at my blog at

« on: September 21, 2010, 09:15:30 AM »
Visions Of Chaos is a professional high end software application for Windows. It is simple enough for people who do not understand the mathematics behind it, but advanced enough for fractal enthusiasts to tweak and customise to their needs. It is the most complete all in one application dealing with Chaos Theory available. Every mode is written to give the best possible quality output. There are thousands of sample files included to give you an idea of what Visions Of Chaos is capable of.

Aparapi is an API for expressing data parallel workloads in Java and running those workloads on a compatible GPU if possible. Where your workload actually ends up running depends on

    * whether you have the ATI Stream SDK installed
    * whether you have a compatible GPU
    * whether your Java parallel code avoids any constructs that would make it untranslatable to OpenCL™. These restrictions are detailed in the Aparapi Readme file.

If your code and your target platform meet all of the above, Aparapi will translate your workload to OpenCL™ and will run your workload on the GPU. Otherwise, your same code will still run as a parallel workload using a Java Thread Pool and will be able to take advantage of multiple cpu cores if you have them.

3D-Tech News Around The Web / OpenCL – Portable Parallelism Tutorial
« on: September 21, 2010, 06:17:36 AM »
Architecture and balance ratios are key concepts that are essential to understanding OpenCL device performance. In particular, the bandwidth of the link between the host and OpenCL device, along with the memory bandwidth of the device can be key performance metrics. In some cases, either of these hardware characteristics can make it too expensive to move a calculation from the host onto an OpenCL device. However, many problems require enough computation per data item transferred to greatly speed OpenCL applications.
Finally, this tutorial has provided a quick and basic introduction to OpenCL along with an example code that can run on both CPU and GPU device types. Try it and see how it works.

3D-Tech News Around The Web / Unigine: CUDA vs OpenCL vs SPU Part IV

Finally I've got radix sort implementation which is working on AMD OpenCL. ... And now we have new more interesting results 
Time of GPU sorting includes time of data downloading from video memory. Sorted structure is single uint2 array for bitonic sort, and two int arrays for radix sort.

When the FirePro series based on AMD's Evergreen GPU was first hitting the street they had a huge lead in performance and feature set making them the perfect upgrade for professional users looking for the best available product.  Since then NVIDIA has released their Quadro update based on the Fermi architecture and has taken back some of the spotlight; AMD still has the edge in features but the performance edge probably leans towards NVIDIA for now.  That being said, if you are in the market for a multi-display card, there is nothing even close to the FirePro V9800 and its 6 DisplayPort outputs except maybe AMD's own V8800 with four.  AMD is hoping to capitalize on that customer need with a solution that can dramatically lower their costs and provide new development and display experiences.

POWERVR Insider SDK has some nice samples and a GUI with a comprehensive log.
The videos from native demos look still better though.
