AMD Radeon Adrenalin 21.9.1 – Controller Brings Intelligent Access Memory to Radeon RX 5000

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

AMD Smart Access memory for Radeon RX 5000

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

After AMD officially released full access to VRAM for the Ryzen 3000 in March and BIOS updates also rolled out the feature on the X470 and B450, as well as the AMD Ryzen Threadripper 3000 series HEDT processors, AMD is now officially delivering. green to Radeon. RX-5000 series.

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

Optimized for Deathloop and Call of Duty

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

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

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

• Visual artifacts may be observed in PAYDAY ™ 2 during gaming on some AMD Graphics products such as Radeon ™ RX 6800 XT.
• Connecting two displays with large differences in resolution / refresh rate 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 screen resolution and refresh rate are set to specific settings such as 1080p at 60Hz.
• When 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 quickly looks around an environment with your character.

AMD Radeon Adrenalin 21.9.1 – Release Notes

The action RPG Horizon Zero Dawn (test) and Battle Royale PlayerUnknown’s Battlegrounds continue to cause graphics controller issues.

• Open Broadcaster Software ™ can continue to run in the background after a user ends a recording session and closes the application.
• Driver timeouts can be experienced while playing a game and streaming 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 cause the driver to time out or crash on some AMD graphics products such as the Radeon ™ RX 6700 XT.
• Enhanced sync can cause a black screen to occur when enabled in some games and system settings. Any user who may have problems with Enhanced Synchronization enabled should disable it as a workaround.
• Radeon performance metrics and logging functions may intermittently report extremely high and incorrect memory clock values.

AMD Radeon Adrenalin 21.9.1 – Release Notes

Download at ComputerBase

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

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