Intel updated their Sandy Bridge drivers at IDF. Intel has refreshed its generic Sandy Bridge graphics driver to version 15.22.50.2509 for 32-bit Windows Vista and 7 and version 15.22.50.64.2209 for 64-bit Windows Vista and 7. some of the fixes include are WebGL rendering problems in Firefox and Chrome, and various OpenGL enhancements. Details are available on the online Intel PDF.

Dr. Jon Peddie from Jon Peddie Research has tried to make sense of the recent WebGL security issues raised by various companies. He writes “If we can never expose any graphics drivers to the web - we can never have ANY GPU graphics in the browser - and that’s not going to happen.” Jon Peddie was recently named one of the most influential industry analysts, who is frequently quoted in trade and business publications, and contributes articles to numerous publications as well as appearing on CNN and TechTV.

NVIDIA is proud to announce the immediate availability of OpenGL 4 drivers for Linux as well as OpenGL 4 WHQL-certified drivers for Windows. Additionally, support for eight new extensions is provided:

  • ARB_texture_compression_bptc – provides new texture compression formats for both fixed-point and high dynamic range floating-point texels.
  • EXT_shader_image_load_store - allows GLSL- and assembly-based shaders to load from, store to, and perform atomic read-modify-write operations to texture images.
  • EXT_vertex_attrib_64bit - provides OpenGL shading language support for vertex shader inputs with 64-bit floating-point components and OpenGL API support for specifying the value of those inputs.
  • NV_vertex_attrib_integer_64bit - provides support for specifying vertex attributes with 64-bit integer components, analogous to the 64-bit floating point support added in EXT_vertex_attrib_64bit.
  • NV_gpu_program5 - provides assembly programmability support for new hardware features provided by NVIDIA’s OpenGL 4.0-capable hardware in vertex, fragment, and geometry programs.
  • NV_tesssellation_program5 - provides assembly programmability support for tessellation control and evaluation programs.
  • NV_gpu_shader5 - provides a superset of the features provided in ARB_gpu_shader5 and GLSL 4.00. This includes support for a full set of 8-, 16-, 32-, and 64-bit scalar and vector integer data types, and more. Additionally, it allows patches (as used in tessellation) to be passed on to the geometry shader, used as input to transform feedback, and rasterized as a set of control points.
  • NV_shader_buffer_store – extends the bindless graphics capabilities of the NV_shader_buffer_load extension. This extension provides the ability to store to buffer object memory, and to perform atomic read-modify-write operations, using either GLSL- or assembly-based shaders.

The official feedback thread is available in the OpenGL Discussion Forums. The drivers and extension documentation can be downloaded from http://developer.nvidia.com/object/opengl_driver.html

NVIDIA and its ecosystem partners will deliver, over the next few months, the industry’s broadest set of software releases to developers using GPU Computing in their work. These updates feature major releases across a broad spectrum of GPU Computing development languages, tools and libraries. NVIDIA is releasing its R195 driver which includes new extensions to its OpenCL 1.0 conformant driver and toolkit. The new extensions include support for double precision, OpenGL interoperability and the new OpenCL Installable Client Device (ICD).

NVIDIA has released the first public OpenCL conformant GPU drivers as well as a powerful performance profiling tool and an OpenCL Best Practices Guide. The OpenCL Visual Profiler uses the extensive performance instrumentation in NVIDIA’s OpenCL drivers and hardware performance signals designed into NVIDIA GPUs to provide developers with insight into performance bottlenecks and opportunities for optimization. The OpenCL Best Practices Guide designed to help OpenCL developers programming for the CUDA architecture implement high performance parallel algorithms and understand best practices for GPU Computing. The OpenCL drivers, Visual Profiler, and Best Practices Guide are all available on the NVIDIA developers website.
