AMD has released its new Adrenalin 19.11.1 driver which has been optimized for the PC version of Red Dead Redemption 2.

The Green team already released its new game-ready driver for Red Dead Redemption 2 on PC and AMD’s new Radeon Software Adrenalin 2019 Edition 19.11.1 is out now as well. Alongside optimizations for Rockstar Games’ masterpiece, the new driver adds several new Vulkan extensions.

AMD Adrenalin 19.11.1 Driver Release Notes

Support For

  • Red Dead: Redemption 2

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
    • This feature bit allows invocations to perform cluster operations such as add, mul, min, max, and, or, xor among partitions of a subgroup. The operations are only performed within the subgroup invocations within a partition.

Fixed Issues

  • Some users may be unable to connect their Twitch™ account through the Connect page in Radeon Settings for live streaming.
  • The Outer Worlds™ may sometimes experience an application crash when opening the characters inventory screen.
  • The Outer Worlds™ may experience character models being rendered incorrectly on the inventory screen.
  • Frame Rate may cap or remain limited to 60 fps in some Vulkan® API games.
  • OBS streaming may experience heavy frame drops when using AMF encoding.
