Radeon Software Adrenalin 2019 Edition 19.11.1 Highlights. Support For Red Dead: Redemption II Added Vulkan® Support VK_KHR_timeline_semaphore This extension introduces a new semaphore type that uses an integer payload to identify a point in a timeline. The extension supports querying the semaphore, host wait/signal operations, and device wait/signal operations. VK_KHR_shader_clock This extension allows a shader to query a real-time or monotonically incrementing counter at the subgroup level or across the device level. VK_KHR_shader_subgroup_extended_types This extension enables the nonuniform group operations in SPIR-V to support 8-bit integer, 16-bit integer, 64-bit integer, 16-bit floating-point, and vectors of these types. VK_KHR_pipeline_executable_properties This extension allows debugging and performance tools and applications in general to query properties and statistics about the pipeline compilation process. VK_KHR_spirv_1_4 This extension allows the use of SPIR-V 1.4 shader modules, which in turn allows easier translation from high level languages into spirv. VK_EXT_subgroup_size_control This extension enables an implementation to control the subgroup size by allowing a varying subgroup size and also specifying a required subgroup size. The optional feature to allow full compute subgroups is enabled. Clustered Subgroup Operations Fixed Issues Some users may be unable to connect their Twitch™ account through the Connect page in Radeon Settings for live streaming.
