Release highlights since 340.24:
 
  • Added support for the following GPUs:
     
    • GeForce 830A
    • GeForce 810M
  • Fixed a bug that caused disabled displays to be implicitly included in the target selection for some queries and assignments on the nvidia-settings command line interface, in the absence of any explicit target selection.
  • Added a new attribute to the NV-CONTROL API to query the current utilization of the video decode engine.
  • Fixed a bug where the Exchange Stereo Eyes setting in nvidia-settings didn't work in certain stereo configurations.
  • Worked around a Unigine Heaven 3.0 shader bug which could cause corruption when tessellation is enabled by implementing an application profile that uses the "GLIgnoreGLSLExtReqs" setting.  See the documentation for the __GL_IGNORE_GLSL_EXT_REQS environment variable for more details.
  • Fixed a memory leak when destroying EGL surfaces.
  • Added support for multiple simultaneous EGL displays.
  • Removed support for G8x, G9x, and GT2xx GPUs, and motherboard chipsets based on them. Ongoing support for new Linux kernels and X servers, as well as fixes for critical bugs, will be included in 340.* legacy releases through the end of 2019.
  • Fixed a bug that could cause nvidia-installer to unsuccessfully attempt to delete the directory containing precompiled kernel module interfaces, on packages prepared with --add-this-kernel.
  • Updated nvidia-installer to log uninstallation to a separate file from the installation log, and to attempt uninstalling previous driver installations using the installer program from the previous installation, when available.

AMFS: Adaptive Multi-Frequency Shading for Future Graphics Processors

We propose a powerful hardware architecture for pixel shading, which enables flexible control of shading rates and automatic shading reuse between triangles in tessellated primitives. The main goal is efficient pixel shading for moderately to finely tessellated geometry, which is not handled well by current GPUs. Our method effectively decouples the cost of pixel shading from the geometric complexity. It thereby enables a wider use of tessellation and fine geometry, even at very limited power budgets.The core idea is to shade over small local grids in parametric patch space, and reuse shading for nearby samples. We also support the decomposition of shaders into multiple parts, which are shaded at different frequencies. Shading rates can be locally and adaptively controlled, in order to direct the computations to visually important areas and to provide performance scaling with a graceful degradation of quality. Another important benefit of shading in patch space is that it allows efficient rendering of distribution effects, which further closes the gap between real-time and offline rendering.

The Tegra Android Development Pack (TADP) is a single package that installs all software tools and sets up an Android development environment required to developing for Android on NVIDIA’s Tegra platform (SHIELD family of devices, Xiaomi MiPad, Tegra NOTE7, Tegra Developer Kits, Google Nexus 7, etc...). TADP 3.0r2 is the first to support the all-new NVIDIA SHIELD tablet and includes brand new versions of Developer Tools (Tegra Graphics Debugger, Tegra System Profiler, Nsight Tegra, Visual Studio Edition).

Actually the installer failed on my rig, so installed the samples manually.
Most new samples especially compute samples fail on Adreno 320 due to missing OpenGL ES 3.1

 An investigation of fast real-time GPU-based image blur algorithms   

  In this blog post I'm going to start exploring the topic of blur filters. My original intention was to…
-    Provide an overview and optimization ideas for a few of the popular real time image blur filters, applicable on very different range of hardware (from sub-4W mobile device GPUs to high end 250W+ desktop GPUs).
-    Give an example of the techniques that runs on Windows Desktop OpenGL and Android OpenGL ES 3.0 and 3.1, including compute shader use on OpenGL ES 3.1.

Feature Highlights of the AMD Catalyst 14.7 RC Driver for Windows
  • Includes all improvements found in the AMD Catalyst 14.6 RC driver
  • AMD ​CrossFire and AMD Radeon Dual Graphics profile update for Plants vs. Zombies​​
  • Assassin's Creed IV - improved CrossFire scaling (3840x2160 High Settings) up to 93%
  • Collaboration with AOC has identified non-standard display timings as the root cause of 60Hz SST flickering exhibited by the AOC  U2868PQU panel on certain AMD Radeon™ graphics cards. A software workaround has been implemented in AMD Catalyst 14.7 RC driver to resolve the display timing issues with this display. 
    • Users are further encouraged to obtain newer display firmware from AOC that will resolve flickering at its origin.
    • Users are additionally advised to utilize DisplayPort-certified cables to ensure the integrity of the DisplayPort data connection.​​

NVIDIA FlameWorks is a system for generating cinematic fire, smoke and explosion effects for games. It combines a state-of-the art grid-based fluid simulator with an efficient volume rendering
engine.
 
The simulator uses a highly optimized solver which enables the simulation of high resolution grids in real-time. It supports collisions with standard primitives and includes a combustion
model for generating flame effects. The system is highly customizable and supports user defined emitters,forcefields and collision objects.
 
The GTC 2014 fire demo demonstrates the cinematic quality of fire/smoke together with ray marched reflections on the ground as well as interaction with a sphere. The demo uses a 512x256x256 voxel grid, meaning that 32M voxels are updated every frame and runs at more than 30fps on a GeForce 780TI.
 
For actual game use cases the voxel grid size is scalable and can be used with lower resolutions as well.
 
No Particles were used in the making of the demo.
