With the new AMD Radeon Adrenalin 21.9.1, the manufacturer is now officially bringing full access to the AMD Smart Access Memory (test) video memory, implemented with the help of the free PCIe technology Resizable BAR, to graphics cards with RDNA-based GPUs of the Navi 10 and type Navi 14 from the AMD Radeon RX 5000 series.

Originally intended exclusively for the combination of Zen 3 alias AMD Ryzen 5000 (test), RDNA 2 alias AMD Radeon RX 6000 (test) and AM4 motherboards with the chipsets X570 and B550 (test), they had detailed test results from the ComputerBase community -Forums showed early on that AMD’s SAM also works with Zen +, Zen 2 and older graphics cards.

After AMD officially released full VRAM access for Ryzen 3000 in March and BIOS updates also released the feature on the X470 and B450 as well as the HEDT processors of the AMD Ryzen Threadripper 3000 series, AMD is now officially giving the go-ahead for the Radeon RX-5000 series.

As community member “WebBeat84” reports, the driver model is also being used WDDM in the new version 3.0 as well as the overclocking of GPU and CPU supported, provided that both components come from AMD.

Optimized for Deathloop and Call of Duty

In addition to SAM for the first RDNA generation, the official release notes also list optimizations for the action adventure Deathloop (system requirements) and the open beta of Call of Duty Vanguard as well as the obligatory error corrections and optimizations.

Support For

• 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 also 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 be 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 @ 60Hz.
• 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.

AMD Radeon Adrenalin 21.9.1 – Release Notes

The action role-playing game Horizon Zero Dawn (test) and the Battle Royale PlayerUnknown’s Battlegrounds continue to cause problems with the graphics driver.

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.

AMD Radeon Adrenalin 21.9.1 – Release Notes

Download on ComputerBase

The AMD Radeon Adrenalin 21.9.1 appears exclusively for Windows 10, but can also be used without any problems for the current Windows 11 Insider Preview Build 22454 and can be downloaded as usual directly below this message from the download area of ​​ComputerBase or from the manufacturer’s website from AMD will.

Users who use an AM4 system with AMD Ryzen or a current APU from AMD should also install the linked new AMD chipset driver v3.09.01.140, which now officially supports Windows 11 for the first time.

The editors would like to thank community member “Rock Lee” for pointing this out.
