What is Intel® Processor Graphics?

Intel® Processor Graphics refers to the technology that provides graphics, compute, media, and display capability for many of Intel’s processors, such as the 4th Generation Intel® Core™ Processor family of products. Within Intel, architects colloquially refer to Intel® Processor Graphics architecture as simply “Gen”, short for Generation. A specific generation of the Intel® Processor Graphics architecture may be referred to as “Gen6” for generation 6, or “Gen7” for generation 7, etc. The branded products Intel® HD Graphics 4600, Intel® Iris™ Graphics 5100, and Intel® Iris™ Pro Graphics 5200 are all derived from instances of Intel® Processor Graphics Gen7.5 architecture. Similarly Intel® HD Graphics 5300 derives from Intel® Processor Graphics Gen8.

General Discussion / How to shutter both eyes of VIEWPixx glasses at the same time
« Last post by esmeraldahl56 on September 23, 2014, 04:50:04 PM »
Hello everybody!

I have a monitor and a 3D glasses from VIEWPixx, and I would like to control the opacity (shutter) time of the glasses in order to control when the subject can see and when cannnot. This obturation, should be simultaneous in both eyes and would not require any syncronization with the monitor, since I do not want to produce any 3D effect.

Do you know if this is possible? Could you indicate me where can I get information on how to do it?

Thank you very much in advance!!

  • GL_NV_framebuffer_mixed_samples and GL_EXT_raster_multisample - target-independent multisampling control and mixed samples: this feature adds a lot of flexibility to the multi-sampled rasterization, and decouples the rasterization sampling frequency (which can be set explicitly) from the actual framebuffer storage. It enables rasterization to operate at higher sampling frequency than the number of samples in the target color render buffers, and it supports both depth and stencil testing at this frequency, if the corresponding depth and stencil buffers are sampled accordingly (it must be a multiple of the number of samples in the color buffers).
  • GL_NV_fragment_coverage_to_color - coverage to color conversion: this allows using ROP to automatically convert the post depth-/stencil-/alpha- test coverage mask into a color and write it into a color render target.
  • GL_EXT_post_depth_coverage - post-depth coverage: this extension allows the fragment shader to get the post depth-test coverage mask of the current fragment as input (gl_SampleMaskIn[]).
  • GL_NV_sample_mask_override_coverage - multisample coverage override: the standard GL behavior for FS output coverage mask (gl_SampleMask[]) is to AND it with the actual primitive input coverage mask. This extension disables this operation.
  • GL_NV_sample_locations - programmable sample locations: Allows applications to explicitly set the location of sub-pixel samples for multisample rasterization, providing fully programmable sampling patterns.
  • GL_NV_conservative_raster - conservative rasterization:  It allows rasterization to generate fragments for any pixel touched by a triangle, even if no sample location is covered on the pixel.
  • GL_NV_fragment_shader_interlock - fragment shader interlock: This extension exposes an hardware-accelerate critical section for the fragment shader, allowing hazard-free read-modify-write operations on a per-pixel basis.
  • GL_NV_fill_rectangle: screen-space bounding-box rasterization: this allows rasterizing the axis-aligned screen-space bounding box of submitted triangles, disregarding the actual triangle edges.
  • GL_NV_geometry_shader_passthrough - geometry shader passthrough: this extension allows to write more efficient geometry shaders in the case there is a one-to-one mapping between input and output primitives.
  • GL_EXT_sparse_texture2: Enhanced sparse textures: this new extension adds the ability to retrieve texture access residency information from GLSL, to specify minimum allocated LOD to texture fetches and to return a constant zero value for lookups into unallocated pages.
  • GL_EXT_texture_filter_minmax - texture Filter min/max: exposes a new sampler parameter allowing to perform a min or max reduction operation on the values sampled inside a texture filtering footprint.
  • GL_NV_shader_atomic_fp16_vector - FP16 global atomics: This extension provides a set of new atomic operations operating on 2 and 4 components vectors of 16b floating point values for images, bindless pointers to global memory and storage buffers.

Hi! (Sorry for the late reply) Yes that worked. I have then narrowed it down to this plugin: plugin_gxl_python_27_x64.dll If I remove that one from the plugins folder then it works :)

In our 21-year quest to bring the most realistic 3D graphics to gamers, NVIDIA has introduced a number
of innovations. With its hardware transform and lighting engine, NVIDIA’s GeForce 256 ushered in the
era of the GPU in 1999, bringing T&L support to consumer graphics for the first time. In late 2006 with
the G80 GPU and the GeForce 8800 GTX graphics board, CUDA and the formalization of GPGPU
computing as we know it today was first brought to the world. More recently, in 2010 we launched the
GeForce GTX 480—our first GPU built using the Fermi graphics architecture. GeForce GTX 480
incorporated fifteen parallel tessellation units, enabling dramatic speedups in geometry processing
compared to prior GPUs. With great strides in architectural efficiency, Kepler GPUs delivered
significantly improved performance and power efficiency when introduced in 2012. 
Earlier this year we launched the GeForce GTX 750 Ti, our first GPU from the Maxwell architectural
family. Maxwell GPUs were designed from the ground up for extreme power efficiency and exceptional
performance per watt consumed. In many DX11 applications, the GTX 750 Ti is capable of matching or
even beating the performance of our once flagship GeForce GTX 480, while consuming only a fourth the
power. Thanks to its remarkable power efficiency, our first generation Maxwell GPUs were ideal for use
in power-limited environments like notebooks and small form factor PCs, in addition to mainstream
desktops.
NVIDIA’s latest GPU, GM204, is the first to use the full realization of our 10th
 generation GPU
architecture, Maxwell. Our design goals for GM204 were to deliver:
  Extraordinary Gaming Performance for the Latest Displays
  Incredible Energy Efficiency
  Dramatic Leap Forward In Lighting With VXGI
Extraordinary Gaming Performance for the Latest Displays
