Nuova release dei driver video Radeon, versione 21.3.1, con un interessante changelog e importanti aggiornamenti per le tecnologie Radeon Boost (supporto DX12 e analisi tramite VRS) e Radeon Anti Lag (anche quest’ultimo ora supportato da DX12), oltre che ottimizzazione di DOOM Eternal: The Ancient Gods – Part Two e, ovviamente, la compatibilità con RX 6700 XT uscita ieri 18 marzo. (si fa per dire)

Oltre a questo, sono stati corretti:

  • Radeon Software may sometimes have higher than expected CPU utilization, even when a system is at idle.
  • A system hang or crash may be experienced when upgrading Radeon Software while an Oculus™ VR headset is connected to your system on Radeon GCN graphics products.
  • Minecraft™ DXR may exhibit corrupted or missing textures when ray tracing is enabled on Radeon RX 6000 series graphics products.
  • An application crash may occur in Call of Duty™: Modern Warfare with ray tracing on Radeon RX 6000 series graphics products.
  • Lighting fails to render correctly on Radeon RX 6800 series graphics products in Star Citizen™.
  • A black screen may occur when enabling and disabling Enhanced Sync while vsync is enabled in some Vulkan® API games.
  • A black screen or system hang may occur on Hybrid Graphics systems for some Vulkan® API games when Enhanced Sync is enabled.
  • Bethesda™ launcher may experience an application crash on startup when launching some games.
  • Users may be unable to create a new scene in the Radeon Software Streaming tab on first launch or after a settings factory reset.
  • Game specific performance tuning profiles may fail to load when a global performance tuning profile has been created or set.
  • Disabling HDCP support and performing a factory reset and/or system restart may sometimes trigger a system crash.
  • Epic Games™ social overlay or launcher may exhibit color corruption.
  • Xuan-Yuan Sword VII™ may experience an application crash with DirectX®12 ray tracing enabled on Radeon RX 6000 series graphics.
  • Color corruption may be experienced in Cyberpunk 2077™ when Radeon Boost is enabled.
  • Display flicker or corruption may occur on high refresh rate/resolution multi-monitor system configurations on Radeon RX Vega series graphics.
  • Audio loss or cutout may intermittently occur on some TV displays when Windows® audio is set to use 5.1 or 7.1 speaker configurations.

Una release interessante, che introduce inoltre un nuovo perforrmance tool in grado di valutare la Gpu per consolidare al volo i profili creati e quindi fare fine tuning della stessa.


Vengono introdotte anche diverse nuove estensioni Vulkan:

  • VK_KHR_synchronization2
    This extension modifies the original core synchronization APIs to simplify the interface and improve usability of these APIs. It also adds new pipeline stage and access flag types that extend into the 64-bit range. Pipeline stages and access flags are now specified together in memory barrier structures, making the connection between the two more obvious. Additionally, Layout transitions have been simplified by providing generic layouts, which are contextually applied based on the image format. Events are made more efficient as well as they include memory dependency information when they are set on the device. Furthermore, Queue submission has also been changed to wrap command buffers and semaphores in extensible structures, which incorporate changes from Vulkan 1.1, VK_KHR_device_group and VK_KHR_timeline_semaphore. This adds a pipeline stage to the semaphore signal operation, mirroring the existing pipeline stage specification for wait operations.
  • VK_EXT_4444_formats
    This extension defines the VK_FORMAT_A4R4G4B4_UNORM_PACK16_EXT and VK_FORMAT_A4B4G4R4_UNORM_PACK16_EXT formats for compatibility with other graphics APIs to help with porting without having to resort to swizzling.
  • VK_EXT_conditional_rendering
    This extension allows conditional draws, compute dispatches or clears based on a value in command buffer memory. These commands could be discarded without the application’s intervention if the condition is not met, which may result in reduced latency.
  • VK_KHR_sampler_ycbcr_conversion
    This extension provides the ability to perform color space conversions during texture sampling operations for the Y′CBCR color space, which is mainly used for processing inputs from video decoders and cameras. It also adds a selection of multi-planar formats, image aspect plane, and the ability to bind memory to the planes of an image collectively or separately.
