10 We re happy! but we re not satisfied. Us We want Vulkan to be the API of choice on every platform where it is available* and we want it to be available everywhere* Copyright Khronos Group Page 10

11 Challenges and what we re doing about them Copyright Khronos Group Page 11

12 Challenge: Functionality Gaps Vulkan 1.1 is here! Hurray! Actually not very exciting. (It wasn t meant to be) VK_KHR_16bit_storage VK_KHR_bind_memory2 VK_KHR_dedicated_allocation VK_KHR_descriptor_update_template VK_KHR_device_group* VK_KHR_external_memory* VK_KHR_external_semaphore* VK_KHR_external_fence* VK_KHR_get_memory_requirements2 VK_KHR_get_physical_device_properties2 VK_KHR_maintenance* VK_KHR_multiview VK_KHR_relaxed_block_layout VK_KHR_sampler_ycbcr_conversion VK_KHR_shader_draw_parameters VK_KHR_storage_buffer_storage_class VK_KHR_variable_pointers VK_KHR_get_memory_requirements2 Subgroups Protected Memory Plus a robust pipeline of new tech, prioritized by developer / ecosystem feedback Copyright Khronos Group Page 12

13 Challenge: Implementation Quality Ongoing CTS investments Khronos s single largest engineering project Increased focus on shader testing Tooling improvements to aid test case capture Please help! Raise issues and PRs at Copyright Khronos Group Page 13

14 Challenge: Closed Platforms (macos, ios, UWP) Vulkan Portability Initiative Enable running a subset of Vulkan over another API via shim library MoltenVK shim available for macos / ios Open source library: macos SDK: Give us feedback at Caveat Coder WIP. Conformance test program in development GFX-RS shim in development for UWP Copyright Khronos Group Page 14

15 Valve - Dota 2 on macos via MoltenVK Up to 50% performance increase with Vulkan vs native OpenGL Copyright 2018 The Khronos Group Inc. - Page 15

16 Challenge: Issues we don t know about This is where you come in What (if anything) makes it hard for you to use Vulkan successfully? What are the most important problems for us to focus on? We ll take feedback anywhere, any time General issues: Spec issues: Here, on the street, slack, reddit, in the pub, We look forward to hearing from you! Copyright Khronos Group Page 16
