We've updated the Dynamic Resolution Rendering sample with an optimisation to the temporal anti-aliasing (TAA) upscale pass and added a few new features for improved qualitative comparisons focused on TAA.

You can find the updated sample here.

The changes, listed below, are detailed in this pdf.

    Added optimization for temporal anti-aliasing (TAA) when using motion blur, which decreases the time this pass takes by approximately 40%.
    Corrected the velocity scale factor so that if the pixel in the last frame was 1 pixel away it is attenuated by 1⁄2. Previously a constant scale factor was used, which was chosen for the default resolution.
    Added a zoom box for viewing scaled portions of the screen.
    Added a basic TAA mode that does no velocity scaling so any ghosting issues can be found.
    Improved pause mode that correctly renders the previous and current frames to show TAA artifacts clearly in basic mode.
    Added a motion blur toggle so that the effect of motion blur and TAA can be properly considered.
    Added a symmetric TAA toggle.
    Changed pause key from Space to P.

    Fixed a bug that caused OpenGL programs to leak file descriptors when calling exec() on themselves.
    Fixed rendering corruption at the start of new X server generation.
    Added X driver support for RandR 1.2 and RandR 1.3. See "Support for the X Resize and Rotate Extension" in the README for details.
    Extended the MetaMode X configuration option syntax with the following new attributes:
        "Rotation" : specifies the display device's rotation
        "Reflection" : specifies the display device's reflection
        "Transform" : specifies a 3x3 transformation matrix to be applied to the display device
        "ViewPortOut" : specifies the region of the mode in which to display pixels
        "ViewPortIn" : specifies the size of the region in the X screen to display in the ViewPortOut
        For example, "DFP-0: nvidia-auto-select { Rotation=left }".
        See "Configuring Multiple Display Devices on One X Screen" in the
        README for details.
    Removed the "TwinView" X configuration option; the functionality it provided is now enabled by default.

    Previously, the NVIDIA X driver only enabled one display device for an X screen unless "TwinView" was enabled. Now, the NVIDIA X driver enables, by default, as many display devices as the GPU supports driving simultaneously. To limit how many display devices are driven by an X screen, use the "UseDisplayDevice" X configuration option.
    Added a "CurrentMetaMode" attribute to the nvidia-settings command line, to query and set the current MetaMode.

    As an example, these two commands are equivalent:

        xrandr --output DVI-I-2 --mode 1280x1024 --pos 0x0 --output DVI-I-3 --mode 1920x1200 --pos 1280x0

        nvidia-settings --assign CurrentMetaMode= "DVI-I-2: 1280x1024 +0+0, DVI-I-3: 1920x1200 +1280+0"
    Removed overscan compensation configurability from NV-CONTROL and nvidia-settings. This can be configured, with finer granularity, through the ViewPortIn and ViewPortOut MetaMode attributes. See "Configuring Multiple Display Devices on One X Screen" in the README for details.
    Altered mode validation such that for digital display devices the X driver only allows, by default, modes which are reported in the EDID. Previously, the NVIDIA X driver allowed other modes, but implicitly scaled those other modes to one of the EDID modes. Now, only the modes in the EDID are validated and the X driver does not do any implicit scaling. Any desired scaling can be configured explicitly through the new "ViewPortIn" and "ViewPortOut" MetaMode attributes. See "Configuring Multiple Display Devices on One X Screen" in the README for details.
    Removed Flat Panel Scaling configurability in nvidia-settings. Any desired scaling can be configured through the new "ViewPortIn" and "ViewPortOut" MetaMode attributes.
    Hotplug events (specifically, the RRNotify_OutputChange RandR event) are now generated when display devices are connected and disconnected from the GPU. Many desktop environments automatically resize the X desktop in response to these events.
    Added display device name aliases, such that X configuration options that use display device names can refer to a display device by one of several names, including the RandR Output name for the display device. The X log reports the list of aliases for each display device.
    Updated EDID parsing to include more complete support for EDID 1.4 and more recent versions of CEA-861.
    Removed the "Rotate" X configuration option. This was used to statically rotate the X screen. Its functionality is replaced by the "Rotation" MetaMode attribute and RandR 1.2 rotation support. See the README for details.
    Removed the "RandRRotation" X configuration option. This enabled configurability of X screen rotation via RandR 1.1. Its functionality is replaced by the "Rotation" MetaMode attribute and RandR 1.2 rotation support. See the README for details.
    Removed support for the following NV-CONTROL attributes:
        NV_CTRL_GPU_SCALING
        NV_CTRL_GPU_SCALING_DEFAULT_TARGET
        NV_CTRL_GPU_SCALING_DEFAULT_METHOD
        NV_CTRL_DFP_SCALING_ACTIVE
        NV_CTRL_GPU_SCALING_ACTIVE
        NV_CTRL_FRONTEND_RESOLUTION
        NV_CTRL_BACKEND_RESOLUTION
        NV_CTRL_OVERSCAN_COMPENSATION
        NV_CTRL_FLATPANEL_BEST_FIT_RESOLUTION
    Improved rendering performance for RENDER bitmap text.
    Enabled the OpenGL "Sync to VBlank" option by default.
    Added a new option, --restore-original-backup, to nvidia-xconfig. nvidia-xconfig creates a backup of the original X configuration file when modifying an X configuration file that does not appear to have been previously modified by nvidia-xconfig. This option restores a backup of the original X configuration file, if such a backup is found.
    Expose the following additional FSAA modes via NV-CONTROL, nvidia-settings, and through X visuals and GLXFBConfigs:

        16X multisample FSAA on all GeForce GPUs

        Coverage sample FSAA on G80 and above GeForce GPUs

        32X multisample FSAA on G80 and above Quadro GPUs

        64X multisample FSAA on Fermi and above Quadro GPUs
    Enabled conformant texture clamping by default in OpenGL.
    Removed support for the GVO Clone mode NV-CONTROL attributes:
        NV_CTRL_GVO_DISPLAY_X_SCREEN
        NV_CTRL_GVO_X_SCREEN_PAN_X
        NV_CTRL_GVO_X_SCREEN_PAN_Y
    Added a new, higher resolution icon for nvidia-settings.
    Updated the NVIDIA X driver's handling of X configuration options that affect an entire GPU, not just a particular X screen running on a GPU (e.g., "NoPowerConnectorCheck"): for such X configuration options, the X driver will now honor the option on any of the X screens configured on the GPU. Prior to this change, the NVIDIA X driver only honored such options on the first X screen configured on a GPU.
    Added a checkbox to nvidia-settings to control the texture clamping attribute. When the box is checked, OpenGL textures are clamped according to the OpenGL specification. When it is unchecked, GL_CLAMP is remapped to GL_CLAMP_TO_EDGE for borderless 2D textures.
    Removed the "Display" and "X Screen" tabs from the "X Server Display Configuration Page" of nvidia-settings, and added a new "Selection" dropdown menu for selecting X screens or display devices. This makes it easier to select X screens/Displays that are hidden.

Device fission is an addition to the OpenCL* specification that gives more power and control to OpenCL programmers over managing which computational units execute OpenCL commands. Fundamentally, device fission allows the sub-dividing of a device into one or more sub-devices, which, when used carefully, can provide a performance advantage, especially when executing on CPUs.

The newly released Intel® SDK for OpenCL* Applications 2012 is a comprehensive software development environment for OpenCL applications on 3rd generation Intel® Core™ processor family-based platforms. This SDK also provides developers with the ability to develop and target OpenCL applications on Intel CPUs of previous generations using both the Windows* and Linux* operating systems.

Dark Meadow: The Pact – Live The Nightmare on NVIDIA Tegra 3
Ever had one of those nightmares from which you couldn’t wake up? You twist and turn through narrow halls facing unimaginable horrors, hoping only to wake up from this terrifying phantasm. Only this is no nightmare, it’s all too real. That’s how it goes in the latest Tegra 3 gaming title, Dark Meadow.

Direct Playstore link

This is the second Android game powered with Unreal Engine in 2 years (as opposed to Unity3D where you see a dozen new games each week)

Briefly it's a horror game is like "Silent Hill", the most scary thing though is the german localization  :P

TechPowerUp OSD Server: new beta build

Over the last weeks I've been secretly working on reviving this project.
Added the ability to select any font from the system and customize colors etc.
It will enable the OSD in all 32-bit DirectX games (no OpenGL, no 64-bit).
You can change settings by clicking the icon in the systray.
If you have GPU-Z running it will pick up the GPU-Z sensors and add them to the OSD
