The most important thing about accurately benchmarking a game comes down to one word: research. It isn’t often that the first level or in-game benchmark will give an accurate representation of GPU performance. Using one of these aforementioned methods could lead a writer to come up with the wrong conclusion if he takes the easy way out. Knowing the game one is testing through actual playing time is essential. There is no way anyone should be basing a conclusion off of games they aren’t totally familiar with because as we have seen, the risk of projecting the wrong information through incorrect benchmarks is very high indeed. Many wrongfully think it is fine to load up a few stand-alone benchmarks, hope the results line up with gameplay and be done with it.

3D-Tech News Around The Web / Wither DirectDraw?
« on: June 17, 2010, 06:15:36 AM »

The DirectDraw API has been more or less deprecated for game developers since the release of DirectX 9.0 SDK back in 2002. The last time we shipped samples or documentation on DirectDraw  dates back to the DirectX 8.1 SDK. Game developers looking to do 2D rendering should be using Direct3D, or on systems with DirectX 11 the Direct2D API could also be a good choice. The DirectDraw  documentation can still be found on MSDN. A few lingering issues, however, has kept the DirectDraw header and import library in the DirectX SDK for many long years...

In the DirectX SDK (June 2010) release, the DDRAW.H and DDRAW.LIB files are no longer there.

The big question in high-performance computing (HPC) now is: "What about graphics processing units (GPUs)?" While the bigger question is "What about the software?", GPUs are getting more attention.

Release notes
ATI Catalyst™ 10.6 Driver – What’s New?

Compared to 10.6 beta a profile for empires.exe has been added

2148
KitGuru knows that companies spend millions creating the best HD processing set up possible only to see the final image quality shattered by a weak component somewhere in the system.
We spend many hours watching High Definition content and we never stop playing with our ATI and nVidia driver panels to get the quality as high as we can.
All this fiddling might be fun, but can we add any science to the process of deciding on the best picture? HQV Benchmark 2.0 aims to do just that.

Robert Hess has a roundtable discussion with industry experts to help you understand exactly what DirectCompute is and the kinds of software problems that you can apply DirectCompute to leaverage the GPU for computation.

Changes include:

    * Reference Results: changed UI from multiple combo-boxes to single list-view, making it easier to select, view and modify reference results. You can still only select 4 devices for now, with the earliest unselected if you check more than 4.
    * AVX instruction set: extensive support in all benchmarks: Multi-Media (integer & float), Memory Bandwidth (integer & float, buffered and unbuffered/streaming), Cache & Memory (non-streaming). Removed EMMX.
    * OpenCL: unified module supporting all manufacturer versions (ATI, nVidia, etc.), can use multiple cards from multiple vendors in parallel.
    * OpenGL: now supports versions 4.0 and 3.3; ARB native double support on ATI 5800 and nVidia Fermi (previously only ATI specific doubles were supported).
    * Ranking Engine: is now on-line and localised in all the languages Sandra supports.

3D-Tech News Around The Web / GLSL Minifier
« on: June 16, 2010, 05:34:51 AM »

GLSL Minifier is a tool to pack GLSL shader code. It generates a code as small as possible that is equivalent to the input code. The generated code is also designed to compress well. It has been optimized for use with Crinkler, but should perform well with any other compression tool. GLSL Minifier generates a C header file you can include from your code. This file contains the shader code in a compact string and macros to retrieve the name of the uniforms (because they are renamed).

The DirectX SDK (June 2010) release includes the fixes to the DDSWithoutD3DX and DDSWithoutD3DX11 samples I mentioned in earlier posts. The Programmer's Guide for DDS in the Windows DirectX Graphics documentation was also updated to reflect the latest format details.

There is a footnote at the end of the documentation chart that I wanted to expand on, and this is a consequence of D3DX having a long-standing bug in the way it reads and writes 10:10:10:2 format DDS data files.

The Vienna Computing Library (ViennaCL) is a scientific computing library written in C++ and based on OpenCL. It allows simple, high-level access to the vast computing resources available on parallel architectures such as GPUs and is primarily focused on common linear algebra operations (BLAS level 1 and 2) and the solution of large systems of equations by means of iterative methods. The following iterative solvers are implemented:

    * Conjugate Gradient (CG)
    * Stabilized BiConjugate Gradient (BiCGStab)
    * Generalized Minimum Residual (GMRES)

An optional ILU preconditioner can be used, which is at present computed on the CPU and may thus not lead to overall performance gains.

The library interface is similar to that of the ublas library, which is shipped with Boost. The iterative solvers can be used either on the CPU with ublas types or on the GPU using ViennaCL types.

More information can be found on the project homepage located at http://viennacl.sourceforge.net.

This beautiful abbey pack is based on a real abbey based in England, of which optimum care has been taken to reproduce the still standing structures that exist today. The pack is a faithful recreation of the site. Before the pack was produced, a trip was taken to the abbey, of which hundreds of pictures where taken, to carefully recreate the buildings and maintain total authenticity. All pack pieces come as separate elements, so you can actually design your own abbey scenario.
