Auto Overclocking for AMD Powered PCs

Gamers who have a PC powered by the latest AMD Ryzen™ 5000 series processor and AMD Radeon™ 6000 series graphics card can now take advantage of a new, simple to use, auto overclocking feature found in AMD Radeon Software. Beginning with our latest version of the Radeon Software Adrenalin ver. 21.9.1, gamers can get a boost in performance from just a simple click of a button.

To access this easy-to-use feature, open up Radeon™ Software using the hotkey ‘ALT’ + ‘R’, navigate to the ‘Performance’ tab found at the top of the window, and select ‘Tuning’ in the sub-tab directly below it.

Radeon Software Support for Microsoft® Windows® 11

Windows 11 is just around the corner, and we know many users are participating in the Microsoft® Windows® Insider Program and have access to an early build of Windows. If you’re one of those people, you can now take advantage of all the features found in Radeon Software. Download the new Windows 11 driver from AMD.com to get access to the latest performance optimizations as well as features like Radeon™ Boost, Radeon™ Anti-Lag, and Radeon™ Image Sharpening that can improve performance, reduce latency and enhance visuals. Take advantage of built-in capture and streaming tools, as well as AMD Link, a free app that can let you play your PC games from almost any connected device.

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 the 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

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.

  1. Well, it seems like this is the first Radeon driver that no longer supports my older Radeon 7770. It worked with new drivers up until now, because it was their first card after they transitioned from VLIW to GCN, but I guess nothing lasts forever... My 6870 on the other hand, only one generation older, got it's last driver in 2015 so I guess I can't complain too much.
