3 Copyright 2018 The Khronos Group Inc. - Page 3 Welcome! Thank you - Especially to Ubisoft for hosting us today Tweet away - @c0d1f1ed All the slides and videos will up soon - Please fill out the survey -

4 Copyright 2018 The Khronos Group Inc. - Page 4 Purpose of the day Provide guidance - On the latest Vulkan functionality - Challenging areas Ask questions - Opportunity to question those designing the API - Please don t be shy Get your input - We value your insights - No, really, we do

7 Copyright 2018 The Khronos Group Inc. - Page 7 Who designs Vulkan? The Vulkan Working Group is made up of the industry - GPU vendors, platform vendors, SoC integrators, OEMs, game engine developers and more!

8 Copyright 2018 The Khronos Group Inc. - Page 8 Vulkan is an open standard Vulkan is a cross-vendor, cross-platform API - Implemented by all major GPU vendors - Windows, Linux, Android, Nintendo Switch - Portability initiative on macos / ios Driven by input from developers using Vulkan - Game studio members, and indirectly via dev tech teams - GitHub - Vulkan Ecosystem Forum - Come talk to us if you want to get more involved Croteam Serious Engine

9 Copyright 2018 The Khronos Group Inc. - Page 9 Vulkan titles are shipping Vulkan-only AAA Titles on PC Dota 2 on PC and macos AAA titles on Linux

10 Copyright 2018 The Khronos Group Inc. - Page 10 on mobile and desktop Lineage 2 Revolution Heroes of Incredible Tales Final Fantasy XV Pocket Edition and lots more in the works

11 Copyright 2018 The Khronos Group Inc. - Page 11 What new in Vulkan 1.1? Subgroup Operations - Efficient mechanisms that enable parallel shader invocations to communicate - Wide variety of parallel computation models supported HLSL support (KHR_relaxed_block_layout) - Match HLSL memory data layout constraints - Same HLSL shaders across Vulkan and DX Device Groups (KHR_device_group*) - Enable homogeneous multi-gpu systems - Number of GPUs in system ~transparent to the application

12 Copyright 2018 The Khronos Group Inc. - Page 12 What new in Vulkan 1.1? Cross-process/API sharing (KHR_external_*) - Share memory and sync primitives across API / process boundaries Advanced Compute Functionality (KHR_16bit_storage, KHR_variable_pointers) - Read and write 16-bit quantities stored in GPU memory - Refer to data structures using a restricted form of pointers Multiview (KHR_Multiview) - Render to multiple image views simultaneously - e.g. stereo pairs, cube map faces Descriptor Update Template (VK_KHR_descriptor_update_template) - Update a fixed set of descriptors in a single VkDescriptorSet with a pointer to a user defined data structure

13 Copyright 2018 The Khronos Group Inc. - Page 13 What new in Vulkan 1.1? YCbCr support (KHR_sampler_ycbcr_conversion) - Sample the YCbCr color formatted textures produced by many video codecs - Useful for compositing video streams and mixing them with other graphical content Protected Content - Restrict access or copying from resources used for rendering and display - Secure playback and display of protected multimedia content Maintenance (KHR_maintenance*, KHR_get_memory_requirements2, ) - Bug fixes, cleanup, improved extensibility, better ways to do things

14 Copyright 2018 The Khronos Group Inc. - Page 14 Vulkan 1.1 is shipping today Specifications: For community use and feedback Conformance Tests: For responsive bug fixing and enhancements Tools: compilers, SPIR-V tools, SDK / loader / layers All in open source welcoming issues and pull requests! Conformant Vulkan 1.1 drivers and devices: RADV ANV
