3D-Tech News Around The Web / Indigo Renderer 3.8.2 Beta Release
« on: March 25, 2014, 11:55:35 PM »
In this beta we introduced quite a few optimisations.
One thing we optimised was scene loading times for scenes with lots of large textures.
We also now keep the textures loaded between render runs.

Changelog 3.8.1:
* Improved MLT convergence and raw speed.
* Added multi-threaded texture loading. Greatly speeds up loading times for scenes with lots of hi-res textures.
Also speeds up restarting rendering a lot.
* Greatly increased OpenGL preview rendering speed.
* Added better handling of blend, coating, and double sided thin materials in the OpenGL preview.
* Added some specular shading for Phong in the OpenGL preview.
* Fixed textures not updating in OpenGL preview on realtime changes.
* Fixed online mat browser not showing any materials.
* Fixed IES bug introduced recently.
* Fixed light layer + bidir bug introduced in 3.8.0.
* Fixed bug with blend materials introduced in 3.8.0.
* Fixed saving of arch glass option after enabling in UI.
* Various rendering speed optimisations.

Two GPUs, One Insane Graphics Card: Introducing the GeForce GTX TITAN Z

Continuing the TITAN legacy of supercomputer-inspired performance, NVIDIA CEO Jen-Hsun Huang unveiled the GeForce GTX TITAN Z today at our annual GPU Technology Conference.

Built around two Kepler GPUs and 12GB of dedicated frame buffer memory, TITAN Z is engineered for next-generation 5K and multi-monitor gaming.

With two GK110 chips, TITAN Z is powered by a total of 5,760 processing cores, or 2,880 cores per GPU.

“If you’re in desperate need of a supercomputer  that you need to fit under your desk, we have just the card for you,” Jen-Hsun said.

Unlike traditional dual-GPU cards, Titan Z’s twin GPUs are tuned to run at the same clock speed, and with dynamic power balancing. So neither GPU creates a performance bottleneck.

And that performance is delivered in a card that is cool and quiet, rather than hot and loud. Low-profile components and ducted baseplate channels minimize turbulence and improves acoustic quality.

So if you want to build the ultimate ultra-high definition gaming rig that can harness the power of quad GPUs working in tandem, TITAN Z is the perfect graphics card.

Q: Should I wait to buy a new PC or GPU?
A: No – if you buy a PC with supported graphics hardware (over 80% of gamer PCs currently being sold), you’ll be able to enjoy all the power of DirectX 12 games as soon as they are available.

Q: Does DirectX 12 include anything besides Direct3D 12?
A: Also new is a set of cutting-edge graphics tools for developers.  Since this is a preview of DirectX 12 focused on Direct3D 12, other technologies may be previewed at a later date.
Q: When will I be able to get my hands on DirectX 12?
A: We are targeting Holiday 2015 games.

Q: What hardware will support Direct3D 12 / will my existing hardware support Direct3D 12?
A: We will link to our hardware partners’ websites as they announce their hardware support for Direct3D 12.

Welcome OpenCL™ developers and enthusiasts!  Here you will find a BETA version of our OpenCL 1.2 driver which includes HSA extensions that implement a subset of the functionality from the recently ratified OpenCL 2.0 specification.  This functionality is built on top of the HSA capabilities in AMD’s recently launched 4th generation APU desktop processors (formerly known as “Kaveri”) and include much of the Shared Virtual Memory and Platform Atomics functionality in the OpenCL 2.0 specification.

This BETA release is intended to enable developers who wish to prototype applications using this OpenCL 2.0 functionality now, rather than wait for the AMD driver compatible with OpenCL 2.0. OpenCL 2.0 will be our primary enablement path with a new driver available later this year to enable these features for developers, and so AMD does not plan to deliver a production version of OpenCL 1.2 with these extensions. OpenCL 2.0 will be a major milestone for our industry, and AMD expects it to become the developer tool of choice for heterogeneous computing enablement.

I posted OpenCL 2.0 functions list here

NVIDIA, AMD, Intel Explain How OpenGL Can Unlock 15x Performance Gains
If you want to get a developer’s attention, all you need to do is start dropping whole numbers.
Offer something that’s not 1.2 times better — but two or three times better — you know you’ve got them.

With OpenGL, an open, vendor-neutral standard, developers can get significantly better performance – up to 1.3 times. But with a little tuning, they can get 7 to 15 times more performance.

Aspyr has just released a new update for Civilization V that, among other improvements, takes advantage of the second video card in the Mac Pro.

Mac gamers that play on the Mac Pro will now be able to fully take advantage of the machine’s second video card, which means better visuals and improved performance for the critically acclaimed strategy game. In particular, Civilization V on the Mac Pro will now support 4k monitors while running into fewer crashes. Additionally, the game should run faster (meaning less waiting in between turns in late-game situations).

This update makes Civilization V the only Mac game that currently supports the second video card on the Mac Pro. It should automatically download and install for Steam users; Mac App users can head to the Mac App Store to get the update. For even more info on how to take advantage of the new update, check out the knowledge base article over at our Support site.

Highlights of the AMD Catalyst™ 14.3 Beta V1.0 Driver for Linux:

Resolved Issues:

        [394848] - Xorg crashed  playing AVI video file in VLC player or Parole player
        [394705] - "Nexuiz - Demo3" Ubuntu performance lower than Redhat
        [394704] - "Nexuiz - Demo3" Linux performance  lower than Windows

3D-Tech News Around The Web / DirectX 12: A Major Stride for Gaming
« on: March 20, 2014, 07:23:01 PM »
Microsoft today introduced DirectX 12 at the annual Game Developers Conference (GDC) in San Francisco. DX12 is Microsoft’s latest version of the graphics API that is the dominant standard in the growing, $25 billion PC gaming industry.

Developers have been asking for a thinner, more efficient API that allows them to control hardware resources more directly. Despite significant efficiency improvements delivered by continuous advancement of existing API implementations, next-generation applications want to extract all possible performance from multi-core systems. Developers also want to take direct advantage of advanced GPU hardware features, from which developers are currently insulated to provide fool-proof usage. DirectX 12 was designed from scratch to provide the infrastructure for these advanced applications.

3D-Tech News Around The Web / Blender 2.70 Final is Now Available
« on: March 20, 2014, 05:55:10 PM »
After two release candidates, the Blender Foundation has now released Blender 2.70.

The official release still don't support CUDA sm5.0 kernels.
Blender Artists to the rescue:

Quote from: Rolf
Bug is fixed and 2.70 is out now, so here some updates
Blender 2.70 64-bit Windows with sm_50 kernel Hash: cc2cdfb

Blender 2.70 32-bit Windows with sm_50 kernel Hash 19fcb4d

and for testing a special sm_50 kernel, this kernel enabled subsurface scattering and volume scatter/absorption on 750/ti, only for 64bit.
Vram usage is much higher with this kernel.
Put this file to ...Blender\2.70\scripts\addons\cycles\lib\

Quote from: JuicyFruit
I have also compiled sm_50 kernels for release (both 32 bit and 64 bit)

PowerVR Wizard brings ray tracing to real-time graphics

Today at GDC, the firm announced that its PowerVR Wizard GR6500 graphics processor IP is available for licensing, and it also revealed a major software alliance to enable game developers to take advantage of Wizard's custom ray-tracing hardware.

The Wizard GPU is based on the PowerVR Rogue graphics processor that we're pretty darned certain resides in Apple's latest phones and tablets. More specifically, the PowerVR GR6500 is a ray-tracing enabled version of the PowerVR Series6XT Rogue core...

Crytek Adds NVIDIA GameWorks to “Warface”

We’re announcing today at the Game Developers Conference, in San Francisco, that we’ve teamed up with Crytek to add support for several NVIDIA GameWorks technologies to its hit free-to-play online first-person shooter “Warface,” powered by CRYENGINE, their award-winning game development solution.

CRYENGINE has been praised for over a decade for its advanced technology. It’s the framework behind Crytek’s own hit franchises, including “Crysis” and “Ryse: Son of Rome.” It’s also licensed to top developers, such as NCsoft, XL Games, Tencent and 2K Games.

“Warface” uses CRYENGINE’s advanced graphics and game technology to create a fast-paced, online first-person shooter, featuring intuitive controls and slick gameplay. The addition of GameWorks technologies like NVIDIA PhysX and VisualFX will take the gameplay in “Warface” to a higher plane of realism and engagement.

The Khronos Group today announced a number of new and significant updates to its portfolio of open, royalty free industry standards that enable the authoring and acceleration of parallel computing, graphics, vision, sensor processing and dynamic media on a wide variety of platforms and devices:

    OpenGL® ES 3.1 Specification Released – The next leap in mobile & embedded graphics
    WebCL™ 1.0 Specification Released – Browser-based heterogeneous compute acceleration
    SYCL™ 1.2 Provisional Specification Released – Enabling high-level C++ tools for OpenCL
    OpenCL™ 2.0 Adopters Program Launched – Driving OpenCL 2.0 conformance
    EGL™ 1.5 Specification Released – The essential glue for secure, integrated API rendering

AMD is probably already working on OpenCL 2.0 - at least the recent Catalysts come with Khronos OpenCL ICD 2.0 (OPENCL.DLL)
