A couple of days back, AMD quietly rolled out a feature update to its 20.5.1 Adrenalin driver adding support for hardware-accelerated GPU scheduling (GHS) on select Navi GPUs. Henceforth, the RX 5700 and 5600 series graphics cards, on both desktop and mobile, ie, RX 5700, RX 5600, and RX 5700M, RX 5600M, will support this feature. Sadly, it means Polaris and Vega owners, as well as Ryzen APU owners, will have to wait for a bit longer to get this feature.
GHS is a major feature of WDDM 2.7 introduced in the Windows 10 May 2020 Update (version 2004, build 19041). Rival Nvidia added support for the feature in its latest driver version 451.48 a few days back and AMD has followed suit, albeit only selectively for now.
Since this is only a beta expansion over its previous driver release, AMD hasn't noted any specific bug fixes separately for this version. However, the firm has detailed the issues that are yet to be resolved:
- Oculus™ VR headsets may not display content or may experience severe performance drops with Hardware Scheduling enabled.
- 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.
- Using Edge™ web browser to playback video content with a multi display system configuration may cause a system hang or crash after extended periods of use.
- Performance Metrics Overlay and Radeon WattMan incorrectly report higher than expected idle clock speeds on Radeon RX 5700 series graphics products. Performance and power consumption are not impacted by this incorrect reporting.
- Some games may exhibit stutter intermittently during gameplay on Radeon RX 5000 series graphics products.
- Radeon RX Vega series graphics products may experience a system crash or TDR when performing multiple task switches using Alt+Tab.
- Desktop or In-game corruption may occur intermittently when HDR is enabled.
- Direct ML Media Filters are currently unavailable in Radeon Software Media gallery for video or image content.
- Some users may still experience black screen or system hang issues during extended periods of gameplay.
- Some game titles may experience hitching when Instant Replay is enabled on Radeon RX 5000 series system configurations.
If you own a Navi GPU and want to try GHS, head over to the official release notes page here to download the Radeon Software Adrenalin 2020 Edition 20.5.1 Beta driver. Moreover, AMD's Radeon Software app on Windows can also be used to upgrade to this driver, but do make sure to enable "Optional" updates since this is a beta release.
