Radeon Software Adrenalin 2020 Edition 20.11.3 Highlights
Support For
Immortals: Fenyx Rising
Vulkan

Ray Tracing Extensions
Added Vulkan

Support
VK_KHR_fragment_shading_rate
This extension provides the ability to change the shading rate per fragment. This extension allows for multiple pixels to be shaded via a single fragment shader invocation as opposed to the normal rate of one invocation per pixel.
VK_KHR_acceleration_structure
This extension provides acceleration structures for representing geometry that is spatially sorted. Acceleration structures are the most common way for quickly identifying potential ray intersections by ray tracing techniques.
VK_KHR_ray_tracing_pipeline
This extension introduces ray tracing pipelines along with new shader domains and an indirection table to link shader groups with acceleration structures.
VK_KHR_ray_query
This extension introduces ray queries, which can be used by any shader type outside of the optional dedicated ray tracing pipeline to return traversal results to the calling shader.
VK_KHR_deferred_host_operations
This extension defines the infrastructure and usage patterns for deferrable commands, which allows dependent extensions to defer their own operations. The VK_KHR_deferred_host_operations extension itself does not specify any commands as deferrable.
VK_KHR_pipeline_library
This extension introduces pipeline libraries. A pipeline library is a new special pipeline type that defines a set of pipeline states. It cannot be bound, rather it can be linked into other pipelines.
VK_KHR_shader_terminate_invocation
This extension indicates support for the SPV_KHR_terminate_invocation SPIR-V extension. The SPIR-V extension introduces a new instruction OpTerminateInvocation that allows a shader invocation to immediately terminate, which provides the behavior required by the GLSL discard statement.

, Shadow of the Tomb Raider

, Battlefield

V and Call of Duty

: Modern Warfare may experience intermittent application crashes with DirectX

Raytracing enabled.
Anisotropic Filtering in Radeon

9 applications on RDNA graphics products.
Some games may experience stuttering when set to borderless fullscreen and an extended display is connected running the Netflix

windows store application on RDNA graphics products.
Radeon

recording and streaming features may fail to enable on AMD Radeon

HD 7800 series graphics products.
Modifying the HDMI Scaling slider may cause FPS to become locked to 30.
Performance Metrics Overlay and the Performance Tuning tab incorrectly report higher than expected idle clock speeds on Radeon

RX 5700 series graphics products. Performance and power consumption are not impacted by this incorrect reporting.
Enhanced Sync may cause a black screen to occur when enabled on some games and system configurations. Any users who may be experiencing issues with Enhanced Sync enabled should disable it as a temporary workaround.
