Vulkan API supports multithreading, which is particularly important for mobile platforms. Multithreading enables the system to balance the workload across multiple CPUs, allowing for lower voltage and frequency. The results give considerable energy savings compared to OpenGL ES API. In this video from ARM, you can see just how big a difference there is between OpenGL ES and Vulkan.
1NVIDIA demonstrated at GTC Europe a high-end virtual reality demo of a complete car model. You can explore every detail of the complete car model in virtual reality. To accomplish this, the demo harnesses the NV_gpu_multicast OpenGL extension so two Quadro P6000 can render the left- and right-eye views in parallel and then handles the massive geometric detail with the NV_command_list OpenGL extension.
The schedules for the all-day Khronos BOF Blitz and famous BOF Blitz After Party are now online. Featuring four BOFs on Wednesday July 27th, and a 5th BOF on Tuesday July 26th for Khronos Chapters. We've also compiled a list of all the SIGGRAPH sessions, courses, workshops and BOFs that contain Khronos Technology. Unsurprisingly there is a ton of Vulkan stuff going on this year. Checkout the event page today. Hope to see lots of you in Anaheim during SIGGRAPH!
Tom's Hardware has a nice review on mobile GPUs getting ready for 'Daydream' VR. Among the technologies being used are Khronos' ASTC specification and OpenGL ES. The Adaptive Scalable Texture Compression (ASTC) technology supported by ARM’s latest Mali and other recent GPUs on the market will reduce bandwidth requirements while still delivering decent graphics quality. On the software side, ARM has been optimizing its drivers to reduce latency and ensure fast context switching that is necessary for VR. ARM also enabled a few more OpenGL ES extensions to support efficient rendering to multiple views for both stereo and foveated rendering. Qualcomm's Snapdragon 820 SoC, which comes with the Adreno 530 GPU, has been optimized for VR. It has support for 3D stereoscopic and foveated rendering, the latest graphics APIs such as OpenGL ES 3.2 and Vulkan, and 360-degree 4k video decoding at 60fps.
Doom will receive support for Vulkan, and id Software’s showcase illustrated the GTX 1080 working in tandem with the technology. id Software was one of the first developers to support OpenGL, and it intends to follow that trend with Vulkan.
Intel has released graphics drivers that support the Vulkan 1.0 API for chips running Windows 7, 8 and 10 PCs. The drivers add new beta support for the Vulkan 1.0 API for 6th Generation Intel Core and related processors.
AMD announced the latest update for Radeon Software Crimson Edition 16.3. The driver offers support for the Vulkan API.
Graphics researchers at Samsung Electronics UK have teamed up with mobile graphics specialists Codeplay, Think Silicon and TU Berlin to develop a tool for enabling smartphone batteries to last longer while running advanced video games and using the camera. "Low-power GPU2" (LPGPU2) is a EU-funded research project into low powered graphics devices. It is the work of a specially formed consortium of three companies and one university, all from across the EU, who are collaborating to deliver advances in tools and applications for energy efficient use of mobile GPUs.
Valve has made the SDK for its Steam Link streaming device available for download through GitHub. The Linux-based SDK allows for the creation of native Link applications, and even features OpenGL ES 2, Qt 5.4, and SDL 2 support.
The NVIDIA developer blog has a great article highlighting some of the benefits of Vulkan. A short but worthwhile read for any OpenGL and Vulkan enthusiast. "In this post we want to look at the basic operations that normally happen in a rendering frame and which API mechanisms are used."
