The Android M release:  improving the fundamentals

For the M release, we focused on improving the core user experience of Android, from fixing thousands of bugs, to making some big changes to the fundamentals of the platform
The M Developer Preview includes an updated SDK with tools, system images for testing on the official Android emulator, and system images for testing on Nexus 5, Nexus 6, Nexus 9, and Nexus Player devices. We are excited to expand the program and give you more time to ensure your apps support M when it launches this fall. 

3D-Tech News Around The Web / (WebGL) Star Wars BB8 Droid

Great use of WebGL to show just how the real Star Wars BB8 Droid works


BB-8 is an astromech droid that appears on Star Wars Episode VII - The Force Awakens. It has a ball shaped body and a domed head that resembles that of the R2 series droids, whose most popular unit is R2-D2. BB-8's body rolls independently from the head, which always stays near the vertical axis of the droid.

3D-Tech News Around The Web / MSI Afterburner 4.1.1 Final
« on: May 27, 2015, 05:09:26 PM »
MSI Afterburner 4.1.1 Official Download
- Guru3D and MSI have been working hard on AfterBurner, today we release an updated this revision of Afterburner, this application successfully secured the leading position on graphics card utilities.
Prior to installation please be sure to uninstall your old version of AfterBurner. For Version 4.1.0 AfterBurner received a complete overhaul. That way you can select new skins.

3 year old remote server still works fine.

Game Performance: Geometry Instancing

...Rendering a lot of meshes is desired to create a beautiful scene like a forest, a cheering crowd or an army, but doing so is quite costly and reduces the frame rate. Fortunately this is possible using a simple technique called Geometry Instancing.

Submitting draw calls causes OpenGL to queue commands to be sent to the GPU, this has an expensive overhead which may affect performance. This overhead grows when changing states such as alpha blending function, active shader, textures and buffers.
Geometry Instancing is a technique that combines multiple draws of the same mesh into a single draw call, resulting in reduced overhead and potentially increased performance. This works even when different transformations are required.
Geometry instancing can be used in 2D games for rendering a large number of sprites, or in 3D for things like particles, characters and environment.
If you are drawing the same mesh multiple times in a frame make sure to implement Geometry Instancing in your pipeline! This can greatly reduce overhead and improve performance.

One of the new features in Unity 5.1 is a new unified OpenGL rendering backend.
...Until now, we had a separate renderer for OpenGL ES 2.0, one for OpenGL ES 3.0 (that shared a good deal, but not all, code with ES 2.0) and then a completely different one for the desktop OpenGL (that was stuck in the OpenGL 2.1 feature set). This, of course, meant a lot of duplicate work to get new features in, various bugs that may or may not happen on all renderer versions etc.
So, in order to get some sense into this, and in order to make it easier to add features in the future, we created a unified GL renderer. It can operate in various different feature levels, depending on the available hardware...

Test Driver for HDMI Display Detection Issues

In an ongoing effort to resolve HDMI display detection some users are experiencing, we are releasing a set of test drivers for Sandybridge, Ivybridge, Haswell, and Broadwell based graphics to gather feedback from the Intel Communities on resolving these issues. Some users have been able to resolve this issue by changing the display cable however, this may not solve the issue in all cases. These test drivers provide another option to address this issue.

These test drivers are exactly that, test drivers, and only for testing the HDMI display detection issues. Please be aware that these drivers should not be used on mission critical systems and that we recommend a restore point be created on your system before installing these test drivers.

These test drivers can be installed by extracting the zip file and running the setup.exe file or by using the "Have Disk" method to install.

According to the license agreement, these test drivers are provided "as is" and are not supported by Intel Technical Support or any other department at Intel.

Issues related or due to these drivers are not supported by Intel® Technical Support. However, we at Intel appreciate your feedback in this matter.  Please post all feedback to this thread.

All versions of this test driver can be downloaded here: 

Renders a few frames on AMD Zacate APU, then runs out of memory (i guess) and GPU resets.

On my NVIDIA rig i had to rollback GeForce driver to a version using CUDA 6.x

 NVIDIA VXGI enables real-time global illumination. Adding GI to the scene greatly improves the realism of the rendered images.

Modern real-time rendering engines simulate indirect illumination using different approaches, which include precomputed light maps (offline GI), local light sources placed by artists, and simple ambient light.
