Following previosly revealed roadmap, NVIDIA has updated 3.x generation of PhysX physics engine to version 3.1

List of publicly available free binary PhysX SDKs includes SDK for Windows PC, Linux, Mac OSX (will be added a little later) and, for the first time, Android platforms.

Full story at PhysXinfo

Inspite of being able to install (runtimes are ARMv6), none of the Android samples runs on Qualcomm Adreno 200  :P

All - don't use the current Rage performance driver - package includes very old OGL files, that's why you're seeing corruption etc.

New in Release 276.14:

    NVIDIA Control Panel Updates
        Display
            Revised the ‘Adjust Desktop Size and Position,’ page to provide improved controls for desktop scaling and resizing.
                Includes a preview window.
                Available for all displays (including VGA and HDMI connections).
                Scaling override option
        Workstation
            Under Windows Vista/Windows 7, the Set up SLI Mosaic page uses the same controls as the Set up Mosaic page.
    Display Support
        Added 10-bit Grayscale through DVI for Windows 7  - enables 10-bit Grayscale through DVI for supported monitors such as proprietary medical displays.
    G-Sync
        Enable Direct3D applications to synchronize back buffer presents across multiple GPU's in one system or multiple systems. Multi-Window and Full-Screen applications are supported. Requires NVIDIA G-Sync II and supported Quadro boards, see http://www.nvidia.com/page/quadrofx_gsync.html for more information.
    ODE Driver
        The R275 drivers are the first ‘Optimal Drivers for Enterprise’, a release dedicated to relatively long term stability for ISV certification, OEMs, and Enterprise customers.
    New APIs
        OpenGL path rendering API – enables high-quality text and 2D rendering with OpenGL applications.
    NVIDIA WMI
        This driver release includes NVIDIA WMI, a Windows service as well as decouple WMI provider that allows WMI clients to query and monitor such GPU parameters as GPU fan speed and GPU temperature.
    Workstation application compatibility fixes. Please read the release notes for more information on product support, feature limitations, driver fixes and known compatibility issues.

OpenCL RayTraced Quaternion Julia-Set Example
Last Revision:   
Version 1.6, 2011-09-26
remove usage of make_float3 which is not supported by spec.
Updated Readme file to indicate that this demo will only work on Lion and onwards as it uses float3 vector data type.

The timestamp of the kernel file is March 2010  ??? , however this version runs faster in GPUCapsViewer

OpenCL Histogram Equalization

We're back to the programming and OpenCL examples after SIGGRAPH 2011 which was really interesting.

This time we bring to programmers an interesting example related to image processing: generation of OpenCL accelerated Histogram Equalized pictures.

The method consists of converting a color image into its HSL representation, performing the OpenCL Histogram Equalization on the Luminance channel and then converting back to RBG model for display. In our tests, the GPU overall time was 60x faster  than CPU single-core time.

We intend to ellaborate more on this example and more advanced filters later in the future. Feel free to leave a comment if you're interested in the topic.

I took a sample picture with about 6000x4000 pixels - 21 sec. conventional, 0.7 sec. OpenCL

Change list:

- Improved MSI On-Screen Display server v4.2.3:
- Improved video frames timestamping approach may improve smoothness of videos captured on low framerates
- Improved RTV1 codec provides better compression ratio (significantly better under certain conditions) without affecting the image quality and encoding performance
- Added alternate RTV1 compression mode providing 1.5x - 2x better realtime compression performance at the cost of some minor image quality loss. Video quality slider is now unlocked for RTV1 format, 100% quality selects original compression mode whilst any other value selects new high performance compression mode
- Now MSI Afterburner displays captured video file time, size, per-frame compression ratio and time in the On-Screen Display next to the video capture progress indicator
- Now multithreaded video capture optimization is forcibly disabled by default on single core CPUs
- Kernel mode RTCore driver has been upgraded to v1.6. New driver introduces RivaTuner-styled experimental protected MMIO IOCTLs and removes outdated IOCTLs dedicated for some old and currently abandoned RTCore technology based applications (HIS iTurbo and RMClock)
- Now MSI Afterburner starts significantly faster than before due to optimized I2C devices scanning, cached database access and optimized GPU context switching in profile load routine
- Fixed RTV1 codec installation issue on 64-bit systems
- Now power users may unlock additional hidden video capture formats via the configuration file
- Now screenshot and video capture quality can be adjusted with precise 1% steps instead of 5% steps in the previous version
- Now video capture framerate can be adjusted in [1 FPS; 100 FPS] range with precise 1 FPS steps instead of [25 FPS; 100 FPS] range
- Added Polish localization



I'd like to focus on is one interesting experimental thing in new release:

- Kernel mode RTCore driver has been upgraded to v1.6. New driver introduces RivaTuner-styled experimental protected MMIO IOCTLs and removes outdated IOCTLs dedicated for some old and currently abandoned RTCore technology based applications (HIS iTurbo and RMClock)

New protected MMIO IOCTLs allow MSI Afterburner to hide all low-level access to hardware much deeper into the driver, into separate kernel address space, where it cannot be accessed by unsafe user mode applications like Punkbuster. Protected MMIO can be enabled by editing configuration file and setting MMIOUserMode to 0 (it is set to 1 by default).

I didn't notice obvious changes compared to last version, maybe fixes for latest GPU drivers etc.

SHADOWGUN talk at Unite

Many people were asking for slides from yesterdays “SHADOWGUN: rendering techniques and optimization challenges” talk, so here it is: SHADOWGUN at Unite’11 slides. And sorry for poor projector image.

Confirms Tegra 3 support for Android...


2275
MADFINGER Games  released his extremely anticipated game Shadowgun  for iOS.
Even their competitor AngryMobGames is excited.

Android version - which is said to be Kal-El (NVIDIA Tegra 3) optimized - is scheduled for early October

The latest source code for the LLVM-based compiler Clang—the default compiler in Apple's Xcode developer tools—shows that support has recently been added for Marvell's quad-core, ARM-based Armada XP processor. Since Marvell is targeting the processor for low-power cloud computing applications, why exactly does Apple's version of Clang offer conditional support in its development tool chain?
