AMD today released the latest version of Radeon Software Adrenalin. Version 21.9.1 is feature-packed with stuff enthusiasts are bound to love. To begin with, it introduces Smart Access Memory (PCI Resizable BAR) support for AMD Radeon RX 5000 series (RDNA) graphics processors, when used with a compatible platform. Next up, it adds optimization for "Call of Duty Vanguard Open Beta," and "Deathloop." The drivers also add a handful Vulkan API extensions, including VK_KHR_zero_initialize_workgroup_memory, VK_KHR_shader_integer_dot_product, VK_EXT_shader_atomic_float2, and VK_EXT_load_store_op_none. Perhaps the biggest new feature addition is AMD Auto Overclock.

On machines with AMD Ryzen 5000 series processors and Radeon RX 6000 series graphics, the Auto-Overclock feature detects CPU load, and automatically overclocks it in increments of 50 MHz, beyond the processor's rated maximum boost frequency. Just like manual overclocking, this comes with sizable costs to power consumption and cooling. The feature also automatically overclocks your RX 6000 series GPU. Using the feature is as easy as pulling up the Tuning tab in Radeon Software, and clicking on "Auto Overclock" in the Tuning Control tab. Lastly, Adrenalin 21.9.1 adds support for the upcoming Windows 11 operating system. The software is released alongside AMD's latest 3.09.01.140 Chipset Software, which also add Windows 11 support. A handful bugs have also been fixed, as described below.

• Deathloop
• Call of Duty Vanguard Open Beta
• AMD Smart Access Memory on Radeon RX 5000 Series Graphics

Added Vulkan Support

• VK_KHR_zero_initialize_workgroup_memory: This extension allows implementations to use the null constant initializer on shader workgroup memory variables. This in turn allows applications that run untrusted content to defeat memory-scraping attacks.
• VK_KHR_shader_integer_dot_product: This extension adds support for the integer dot product SPIR-V instructions defined in SPV_KHR_integer_dot_product. The SPV_KHR_integer_dot_product extension allows dot product operations on integer vectors with optional accumulation. In addition to allowing dot product operations for all input vector types, it also allows integer dot product for 4-component vectors of 8-bit integers that are packed into 32-bit integers.
• VK_EXT_shader_atomic_float2: This extension provides shaders with the capability to perform 16-bit floating-point atomic operations on buffer and workgroup memory. It additionally allows floating-point atomic minimum and maximum operations on buffer, workgroup, and image memory.
• VK_EXT_load_store_op_none: This extension allows an application to specify the contents within the render area that will not modified or can be expected to be undefined after rendering.

Fixed Issues

• Visual artifacts in PAYDAY 2 may be observed during gameplay on some AMD Graphics products such as Radeon RX 6800 XT.
• Connecting two displays with large differences in resolution/refresh rates may cause flickering on Radeon RX Vega series graphics products.
• On Radeon RX 5500 XT Graphics, higher than expected memory clock speed and power consumption may be experienced when idle and the display's resolution and refresh rate are set to specific values such as 1080p @ 60 Hz.
• While playing Assassin's Creed Odyssey, driver timeouts or black screens may be experienced on some AMD Graphics products such as Radeon RX 480 Graphics when the user quickly navigates through the game menus or swiftly looks around an environment with their character.

Known Issues

• Open Broadcaster Software may continue to run in the background after a user ends a recording session and closes the application.
• Driver timeouts may be experienced while playing a game & streaming a video simultaneously on some AMD Graphics products such as Radeon RX 500 Series Graphics.
• AMD Radeon Software may crash or become unresponsive while playing some DirectX 11 games such as PlayerUnknown's Battlegrounds with multiple displays connected in extended mode.
• Playing Horizon Zero Dawn for an extended period may lead to a driver timeout or game crash on some AMD Graphics products such as Radeon RX 6700 XT.
• 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.
• Radeon performance metrics and logging features may intermittently report extremely high and incorrect memory clock values.
