Among the newly-published Vulkan talks that will happen at the Game Developers' Conference include high-performance, low-overhead rendering with OpenGL and Vulkan by NVIDIA, D3D12 and Vulkan lessons by AMD, Vulkan fast paths by AMD, and Vulkan on mobile by ARM. More talks are likely to be made public prior to the event, which runs from 14 to 18 March.
There's still no official notice from The Khronos Group when the Vulkan API will launch after being delayed at the end of last year, but it's looking extremely possible that it will launch at or around GDC. At the end of last year I reported some exclusive details on how they're waiting for the "availability of product-quality implementations" before going public as well as the Khronos legal review process. The final version of the specification was finished a few weeks before the end of 2015, not during the summer as some had reported previously. March will mark one year since Vulkan was publicly announced.
More Vulkan details as they become available.
