Certainly, many of you will agree that the addition of GPU PhysX effects to PC games has a positive influence on overall gaming experience and immersion in such titles. But how difficult is to attach hardware accelerated physics effects to a game?

Today, with the help of David Schoemehl, Manager of GPU PhysX Content in NVIDIA, and Johnny Costello, Technical Artist, we will try to give you a brief “behind the scenes” view on the process of enhancing games with extra PhysX content.

Improving the Compute Performance of Video Processing Software Using AVX (Advanced Vector Extensions) Instructions (by Eli Hernandez and Larry Moore)

Modern x86 CPUs permit instruction level parallelism (e.g. SIMD) on register vectors at most 128-bits. Second Generation Intel® Core™ Processors include the first generation of AVX (256-bit operators), which permits increased parallel processing. This paper outlines a case study in which AVX instructions are used to improve the compute performance of a de-saturation algorithm. The paper also discusses how future integer based AVX instructions might be used to further enhance SIMD optimizations and achieve even greater performance benefits on video processing algorithms.

Download and install the Driver from the following location:

AMD Catalyst Driver AMD Radeon HD 7900 series

AMD Radeon™ HD 7900 Series Windows® XP Support

We currently do not officially support Windows® XP on the AMD Radeon™ HD 7900 Series.  An upcoming Catalyst™ release in April 2012 will provide support.

Please note that AMD Crossfire, OpenCL, and AMD Eyefinity will not be supported on the AMD Radeon HD 7900 Series when using Windows XP. New technologies introduced with the new AMD Radeon HD 7900 Series are incompatible with the Windows XP (released 2001) operating system, and will only become fully functional on modern operating systems. Both AMD CrossFireX technologies and OpenCL are support under Windows Vista and Windows 7 for the AMD Radeon HD 7900 Series.

ReadyMap SDK is a free JavaScript library for embedding 3D maps in a web page. Build 3D maps using ReadyMap's API, or turn your OpenLayers or Leaflet maps into 3D globes by adding just a few lines of code!
Works with your data

ReadyMap works with open web-mapping standards like TMS (Tile Map Service) and WMS (OGC Web Map Service). That means that it works with many popular map servers and, of course, our own ReadyMap Server.
3D for a deeper experience

ReadyMap is unique in that is can display 3D map data as well, so you can plot terrain elevation, extruded features, and more. ReadyMap leverages WebGL technology to render high-performance 3D maps.

Out of curiousity i compared Firefox 10 on Windows to Android version.

The day has come
The main idea behind the new separable SSS approach is that you can get very similar results to the full 12-pass approach ... by just using a regular two-pass setup. It can be done in screen space and is really really fast...


FYI the 3D model can be downloaded here

I can't test in #Encog OpenCL Benchmark Utility# because I got error: local ratio cannot be greater than 1 despite default setting.

I forgot they hard coded that bench for their country settings  ::)

In Germany we use a decimal comma instead of a decimal point.
So i need to replace 1.0 with 1 or 1,0

OpenCL™: The Future of Accelerated Application Performance Is Now

OpenCL™, or Open Computing Language, is the first open programming standard OpenCLfor writing software for general-purpose computing across both CPUs and GPUs.

Changing the Game
The ability to perform compute-intensive tasks in parallel, using virtually any multicore processor, opens the door for performance and functionality improvements on an unprecedented scale. If you're working with processingintensive applications in CAD, CAM, CAE, science, DCC or M&E, get ready for OpenCL to change the way you work.

GPUs: Not Just for Graphics Anymore
OpenCL provides an open, uniform programming environment that enables the processing technique known as GPGPU, or general purpose computing on graphics processing units. GPGPU makes it possible to offload certain processingintensive tasks to the GPU, rather than relying on the CPU to do them.

@JeGX and guys:

ALERT! due to OpenCL 1.1 driver issue for nvidia card

Here are some lesser known OpenCL benchmarks if you like to double-check

AMD family 15h-class CPUs use a new micro-architecture that, under specific circumstances,
leads to different performance characteristics compared to previous processor generations.
This white paper describes the nature of instruction-cache cross-invalidations, symptoms and
detection methods, as well as a number of provisions to
ensure optimal performance in this micro-architecture.

AMD family 15h CPUs feature a compute unit architecture
that unites two separate integer-execution units (called
cores) with one wide floating-point unit (FPU) and a shared
decoding front end. This shared front end includes the
level-1 instruction cache (L1 ICache), in contrast to the L1
data cache, which is replicated per integer unit. By design,
the L1 ICache does not allow physical aliases, that is, the
same physical line cannot appear twice. If a second cache
line with the same physical address is about to be stored
in the cache array, the first one will be invalidated and thus
removed from the cache. Under the following conditions,
this leads to an increased number of cache misses, which
decreases the overall performance.

Epic Games, Inc. has released the January 2012 Unreal Development Kit Beta, the latest version of the free edition of Unreal Engine 3 that provides access to the award-winning 3D game engine and toolset used in blockbuster video game development, architectural visualization, mobile game development, 3D rendering, digital films and more. The latest UDK beta is available now at

Unreal Engine Showcase: Chivalry: Medieval Warfare

Developed by Torn Banner Studios using UDK, Chivalry: Medieval Warfare is a multiplayer melee combat game that was recently named a top pick in IndieDB’s "Best Upcoming Game” category in its Indie of the Year competition. The studio’s president, Steve Piggott, explained how UDK allows his team to stay on the cutting edge of visual technology thanks to regular updates. “Instead of developing a game with an engine for two years and then releasing it with two-year-old technology, developers have the opportunity to launch with the latest version and keep updating it even after release. That's a really powerful thing.” Read more.

We have showcases of some of the most outstanding video game, architectural visualization, and mobile apps using UDK at and  Also be sure to check out the Works in Progress and the Released Projects forums.

January UDK Beta Upgrade Notes
Simplygon Mesh Proxy Tool

    New Simplygon Merge Tool for combining static meshes

        Grouped static meshes can be combined into a single static mesh
        This can greatly improve rendering performance
        Materials/textures are automatically collapsed and new UVs are generated
        This tool is fully "non-destructive" - you can modify meshes and remerge, and roll back changes if needed
        Documentation can be found here

Unreal Landscape

        Holes of any shape can be cut into the landscape, allowing designers to create entrances to caverns and other features under the landscape
        The visibility tool can remove or replace individual quads at the highest LOD resolution, with collision added or removed accordingly
        Holes are rendered per-pixel, independently of LOD, so distant holes retain their shape
    Added the ability to save foliage settings to packages and to share them between levels
    Added tool to change component size for existing landscapes
    Hide unused landscape UI when no landscapes are available

Pivot Painter

    A new 3ds Max tool that automatically generates pivot points for mesh vertices, allowing for advanced foliage animation and other effects

        Documentation can be found here

iOS Rendering

    Added support for color grading

    Documentation can be found here

Unreal Editor

    Added a "Reconnect" button to the "Checkout packages" dialog
        The function is disabled when a valid connection is established
        Upon reconnect, the login screen will appear if the connection failed
        Once the connection is restored, the "Checkout" dialog is reloaded
    Altered behavior of the "Convert to Static Mesh" operation
        It not only builds a model from the selected static brushes
        It also builds dynamic brushes (which includes volumes) and builds from the builder brush (if selected)
        It treats these as if they were like additive BSP brushes
    The autosave time is now simply paused during PIE instead of reset
    The editor is now more responsive during lighting builds
    Added a context menu option when selecting multiple actors for assigning the material selected from the content browser
    Auto content saving is now enabled by default for new users and 'content packages to save' can now be specified in the ini
    Lens flare visualizations will now appear when a lens flare actor is created and will update if any visualization properties are changed on the template lens flare
    Made the color picker dialog not modal when changing preview background color for textures
    Unreal Matinee slow-mo tracks will no longer effect viewports in other sub-editor windows (such as Unreal Cascade)
    Made the wireframe rendering in orthographic viewports consistent in both DX9 and DX11
    New packages in Unreal Content Browser are now removed from the “New Packages” collection once they've been saved
    Fixed the “Touch Input Kismet” event in Unreal Kismet so that it sends the proper X and Y values
    When in Kismet’s hit-testing mode, the Kismet block nubs are drawn bigger to make them easier to select without taking up more screen space visually
    Enabled the “Paste Here” right-click menu option for nodes in the Material Editor


    Added support for importing multiple animations from a single FBX file:
    Added new option to ignore missing bones when importing
    Fixed FBX issues with morph curves and animation ranges
