    Added support for the following GPUs:
        GeForce GTX 750 Ti
        GeForce GTX 750
        GeForce GTX 745
        GeForce GTX TITAN Black
    Fixed a regression in the NVIDIA kernel module which caused it to improperly dereference a userspace pointer. This potential security issue was initially reported to the public at:

    http://forums.grsecurity.net/viewtopic.php?f=3&t=3922
    The regression did not affect NVIDIA GPU drivers before release 334.
    Fixed a bug that could cause OpenGL programs to hang after calling fork(2).
    Added support for GPUs with VDPAU Feature Set E. See the README for details.
    On GPUs with VDPAU Feature Set E, VDPAU now supports more robust decode error handling at the cost of a minor performance impact.
    This can be disabled by setting the VDPAU_NVIDIA_DISABLE_ERROR_CONCEALMENT environment variable to 1.
    Added support for application profile rule patterns which are logical operations of subpatterns. See the README for details.
    Added support for a "findfile" application profile feature which allows the driver to apply profiles based on matching files in the same directory as the process executable. See the README for details.
    Improved performance of OpenGL applications when used in conjunction with the X driver's composition pipeline. The composition pipeline may be explicitly enabled by using the ForceCompositionPipeline or ForceFullCompositionPipeline MetaMode options, or implicitly enabled when certain features such as some XRandR transformations, rotation,Warp & Blend, PRIME, and NvFBC are used.
    Fixed a bug that could cause nvidia-settings to compute incorrect gamma ramps when adjusting the color correction sliders.
    Updated the nvidia-settings control panel to allow the selection of display devices using RandR and target ID names when makingqueries targeted towards specific display devices.
    Fixed a bug that prevented some dropdown menus in the nvidia-settings control panel from working correctly on olderversions of GTK+ (e.g. 2.10.x).
    Updated the nvidia-settings control panel to provide help text for application profile keys and suggestions for valid key nameswhen configuring application profiles.
    Updated the nvidia-settings control panel to populate the dropdown menu of stereo modes with only those modes which are available.
    Fixed a bug that could cause applications using the OpenGL extension ARB_query_buffer_object to crash under Xinerama.
    Fixed a bug that caused high pixelclock HDMI modes (e.g. as used with 4K resolutions) to be erroneously reported as dual-link inthe nvidia-settings control panel.
    Fixed a bug that prevented some DisplayPort 1.2 displays from being properly restored after a VT switch.
    Renamed per GPU proc directories in /proc/driver/nvidia/gpus/ with GPU's bus location represented in "domain:bus:device.function" format.
    Added 64-bit EGL and OpenGL ES libraries to 64-bit driver packages.
    Changed format of "Bus Location" field reported in the
    /proc/driver/nvidia/gpus/0..N/information files from "domain:bus.device.function" to "domain:bus:device.function" to matchthe lspci format.
    Fixed a bug in the GLX_EXT_buffer_age extension where incorrect ages would be returned unless triple buffering was enabled.
    Changed the driver's default behavior to stop deleting RandR 1.2 outputs corresponding to unused DisplayPort 1.2 devices. Deleting these outputs can confuse some applications. Added a new option,DeleteUnusedDP12Displays, which can be used to turn this behavior back on.This option can be enabled by running sudo nvidia-xconfig --delete-unused-dp12-displays
    Improved support for the __GL_SYNC_DISPLAY_DEVICE and VDPAU_NVIDIA_SYNC_DISPLAY_DEVICE environment variables in certain configurations. Both environment variables will now recognize all supported display device names. See "Appendix C. Display Device Names" and "Appendix G. VDPAU Support" in the README for more details.
    Improved performance of the X driver when handling large numbers of surface allocations.

General Discussion / EVGA GeForce GTX 750 Ti FTW hands-on review
« on: February 26, 2014, 06:55:18 PM »
Just upgraded my old rig with EVGA GeForce GTX 750 Ti FTW w/ EVGA ACX Cooling

I don't waste your time by repeating benchmarks already shown on major news sites.

Fan-speed detection in Geeks3D programs needs to be updated.
Maxwell stands FurMark easily, only 55°C with 8xMSAA

AMD LEO, FluidMark, TessMark, NVIDIA Alien vs. Triangles, NVIDIA Endless City produce only max. 46°C

GPU-Z always reads DirectX 11.1, even under Windows XP.

NVFLASH support for GM107 begins with v5.142

If you like to have tested some CUDA accelerated apps, let me know.
I suggest to compile them against CUDA 6.0 RC SDK to exploit Maxwell's capabilities.

3D-Tech News Around The Web / NVIDIA G-SYNC Pendulum Demo

G-SYNC Pendulum Demo
With the Pendulum demo, see how NVIDIA G-SYNC changes gaming by eliminating tearing and minimizing stutter and lag, giving you the smoothest, fastest gaming experience.

Simple to install and run, the interactive Pendulum demo lets you see the stutter caused by V-SYNC, the tearing caused with V-SYNC OFF, and then the tear-free, super smooth presentation with G-SYNC. Experiment with different GPU frame rates, camera angles and scene rotation settings to get a real feel for G-SYNC and start to see gaming differently.

With VSYNC selected, change the GPU frame rate. As the frames per second drop below the maximum refresh rate of the monitor, notice the stutter in the pendulum’s swing. With “noVSYNC” selected, try different GPU frame rates and immediately notice tearing on the screen. And with G-SYNC selected, you’ll see a smooth, tear-free image.

3D-Tech News Around The Web / NVIDIA GeForce GTX 750 Ti whitepaper
« on: February 20, 2014, 05:10:55 PM »

NVIDIA’s first-generation “Maxwell” architecture implements a number of architectural enhancements
designed to extract even more performance per watt consumed. The first Maxwell-based GPU is
codenamed “GM107” and designed for use in power-limited environments like notebooks and small
form factor (SFF) PCs. These SFF systems are often used for gaming and home entertainment, with the
most recent example being Valve Software’s recently announced Steam Machines initiative. The first
graphics card that is based on the GM107 GPU is the GeForce GTX 750 Ti. Because of GM107’s
remarkable architectural efficiency, at 1080p resolution a GeForce GTX 750 Ti will frequently match the
performance of our flagship GPU from four years ago, the GeForce GTX 480, but with only a 60W TDP,
consumes a fourth of the power.

Dramatically simplify parallel programming with CUDA 6.0 .

Unified Memory

    Simplifies programming by enabling applications to access CPU and GPU memory without the need to manually copy data. Read more about unified memory.

Drop-in Libraries

    Automatically accelerate applications’ BLAS and FFTW calculations by up to 8X by simply replacing the existing CPU libraries with the GPU-accelerated equivalents.

Multi-GPU scaling

    cublasXT - a new BLAS GPU library that automatically scales performance across up to eight GPUs in a single node, delivering over nine teraflops of double precision performance per node, and supporting larger workloads than ever before (up to 512GB). The re-designed FFT GPU library scales up to 2 GPUs in a single node, allowing larger transform sizes and higher throughput.

Video Processing with AMD’s Media SDK
The Media SDK is more than just codecs! For years now, AMD has provided users who view video on their windows devices access to an ever increasing suite of video quality processing algorithms in order to improve their viewing experience. The video quality processing algorithms (similarly to those provided in CE products such as TVs) goal is to improve the perceptual quality of the video during playback or potentially during operations such as video transcode and video conferencing.
