Radeon Software Adrenalin 2020 Edition 20.9.2 Release Notes

Radeon Software Adrenalin 2020 Edition 20.9.2 Highlights

Support For

• STAR WARS™: Squadrons

Added Vulkan™ Support

• VK_KHR_buffer_device_address
  • This extension is used to query the device address of a buffer to allow for shader access to that buffer’s storage via the SPV_KHR_physical_storage_buffer SPIRV extension.
• VK_EXT_robustness2
  • This extension provides stricter restrictions for handling reads and writes that are out of bounds. It specifies that out-of-bounds reads must return zeros and out-of-bounds writes must be discarded. This extension also adds support for null descriptors.
• VK_EXT_shader_image_atomic_int64
  • This extension extends existing 64-bit integer atomic support to images, which provides more efficient access than buffers. This allows applications to quickly improve their performance with minor changes to their code.

Fixed Issues

• Some games may exhibit stutter intermittently during gameplay on Radeon RX 5000 series graphics products.
• Radeon FreeSync may fail to enable after updating Radeon Software without a system reboot.
• Screen flickering may be observed while MSI Afterburner™ is running or enabled on the system.

• Blocky corruption may be observed in Detroit: Become Human™ on some Radeon RX 5000 series graphics products.
• Using the Movies&TV application to edit video clips may result in green corruption in the clips.
• Performance metrics may report incorrect values for current VRAM usage after an extended period of gameplay.
• With HDR enabled, Windows® desktop may experience flickering, and performing a task switch while in a game may cause colors to become washed out or over saturated.
• World of Warcraft™ may experience corruption issues with anti-aliasing enabled on DirectX®12 API.
• Launching Radeon Software after a driver upgrade, may cause the Auto OC dialogue to appear with “0 Mhz” when the Auto OC feature has been previously enabled on Radeon RX Vega series graphics products.

Known Issues

• 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.
• 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.
• Audio may experience instability when connected through an Audio Video Receiver via HDMI® on Radeon RX 5000 series graphics products.
