We knew that NVIDIA had an impending driver update providing DirectX 11 performance improvements. Launched today, 337.50 still claims significant performance increases over the previous 335.23 version. What was a surprise is GeForce Experience 2.0. This version allows both ShadowPlay and GameStream to operate on notebooks. It also allows ShadowPlay to record, and apparently stream to Twitch, your Windows desktop (but not on notebooks). It also enables Battery Boost, discussed previously.

Personally, I find desktop streaming is the headlining feature, although I rarely use laptops (and much less for gaming). This is especially useful for OpenGL, games which run in windowed mode, and if you want to occasionally screencast without paying for Camtasia or tinkering with CamStudio. If I were to make a critique, and of course I will, I would like the option to select which monitor gets recorded. Its current behavior records the primary monitor as far as I can tell.

I should also mention that, in my testing, "shadow recording" is not supported when not recording a fullscreen game. I'm guessing that NVIDIA believes their users would prefer to not record their desktops until manually started and likewise stopped. It seems like it had to have been a conscious decision. It does limit its usefulness in OpenGL or windowed games, however.

This driver also introduces GameStream for devices out of your home discussed in the SHIELD update.

This slide is SLi improvements, driver-to driver, for the GTX 770 and the 780 Ti.

As for the performance boost, NVIDIA claims up to 64% faster performance in configurations with one active GPU and up to 71% faster in SLI. It will obviously vary on a game-by-game and GPU-by-GPU basis. I do not have any benchmarks, besides a few examples provided by NVIDIA, to share. That said, it is a free driver. If you have a GeForce GPU, download it. It does complicate matters if you are deciding between AMD and NVIDIA, however.

ARM is a company that no longer needs much of an introduction.  This was not always the case.  ARM has certainly made a name for themselves among PC, tablet, and handheld consumers.  Their primary source of income is licensing CPU designs as well as their ISA.  While names like the Cortex A9 and Cortex A15 are fairly well known, not as many people know about the graphics IP that ARM also licenses.  Mali is the product name of the graphics IP, and it encompasses an entire range of features and performance that can be licensed by other 3rd parties.

I was able to get a block of time with Nizar Romdhane, Head of the Mali Ecosystem at ARM.  I was able to ask a few questions about Mali, ARM’s plans to address the increasingly important mobile graphics market, and how they will compete with competition from Imagination Technologies, Intel, AMD, NVIDIA, and Qualcomm.

 

We would like to thank Nizar for his time, as well as Phil Hughes in facilitating this interview.  Stay tuned as we are expecting to continue this series of interviews with other ARM employees in the near future.

Futuremark Teases 3DMark DirectX 11 With Tech Demo Video

Popular benchmarking software developers Futuremark recently posted a video of latest 3DMark tech demo. Premiering in its Windows 8 benchmarking software, the tech demo uses complex volumetric lighting with real time scattering, tessellation, visible particles and clouds of smoke. It also uses fluid dynamics, audio by Pedro Macedo Camacho (who also created the 3DMark 11 soundtrack), ambient occlusion, and post processing. Whew, that’s a lot of shiny graphics!

We posted a few screenshots of the tech demo that showed up online a few weeks ago, and now it seems like the company is ready to show it off in video form. The embedded video below shows a mysterious figure walking through a small town nestled in a canyon with smoke, lava, and a flying robot to keep her company. The graphics are very detailed and the particle and fluid physics look really good. It should do a great job of stressing out your graphics cards when it comes out in the latest 3DMark.

Unfortunately, not much is known as far as specific release dates, or even if it will be called 3DMark 12 (or 3DMark for Windows 8). If you are into benchmarking software though, keep your eyes on Futuremark’s website as they release more details.
