Nuova release dei driver video Radeon, versione 21.9.1 con un interessante changelog e supporto a Deathloop e Call of Duty® Vanguard Open Beta.

Oltre a questo è stata introdotta una modalità di Overclock automatico della Gpu in presenza di Ryzen 5000 e una scheda grafica serie 6000 e il supporto a SAM (Smart Access Memory) anche per RDNA1 ( RX 5XXX), insomma importanti upgrade che testimoniano un eccellente sostegno anche per tutti quei prodotti che non sono nel paniere delle ultime uscite.

Questa release introduce, poi, la compatibilità ufficiale con Windows 11, attualmente in beta e in uscita il 5 ottobre.

Vengono ampliate le estensioni Vulkan con 4 nuove entry:

  • 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.

Corretti, inoltre, i seguenti problemi:

  • 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

Problemi ancora non risolti, ma conosciuti:

  • 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.

Ricordiamo, inoltre, che il supporto è garantito solo alle seguenti architetture:

  • Radeon™ RX 6900/6800/6700/6600 Series Graphics
  • Radeon™ RX 5700/5600/5500/5300 Series Graphics
  • Radeon™ VII
  • Radeon™ RX Vega Series Graphics
  • AMD Radeon™ Pro Duo
  • Radeon™ RX 500 / Radeon 500X Series Graphics
  • Radeon™ RX 400 Series Graphics
