AMD delivers tonnes of new features with their Radeon Software Adrenalin 21.4.1 driver update

AMD has just launched their Radeon Software 21.4.1 driver for Windows-based operating systems, adding new features to the company’s GPU drivers, many bug fixes, and new CPU metrics monitoring options for Ryzen processors. 

One of the largest updates that have come to Radeon Software 21.4.1 is support for AMD’s new AMD Link client for Radeon-powered PCs, which enables PC-to-PC streaming for game and desktop streaming to other devices. This tool can be used for mobile troubleshooting, game streaming and multi-device co-op in some games. 

With AMD’s latest Link Software, AMD has redesigned its streaming technology to deliver stronger visuals and lower latency levels, both of which enable higher quality user experiences. 

AMD’s Radeon Software has also been updated to include custom installation options, allowing users to do a full driver/software installation, a minimal installation or a driver-only installation. AMD has also pioneered a new feature called “Vivid Gaming Display Color Enhancement”, a setting that can counteract the colour deficiencies of certain display types to enable a better visual experience for some Radeon users. 

The full release notes for AMD’s Radeon Software Adrenalin driver are available to read below.

Fixed Issues

– Brightness flickering may intermittently occur in some games or applications when Radeonâ„¢ FreeSync is enabled, and the game is set to use borderless fullscreen.
– SteamVRâ„¢ may experience an application crash when a VR headset is connected on Radeon RX 500 series graphics products.
– Some high refresh rate, high resolution TV displays may experience corruption when connected via HDMI on Radeon RX 6000 series graphics products.
– Applying changes in Radeon Performance Tuning may sometimes fail to take effect for changes made to power tuning.
– Lower than expected performance may be experienced in some CPU intensive workloads or games.
– Global performance tuning overclock profiles may sometimes override game specific performance tuning profiles or cause game specific performance tuning profiles to fail to load on a games launch.
– Radeon Chill may experience lower than expected performance when a game is left idle for an extended period with Radeon Chill enabled.
– Flickering may be observed in Radeon Software performance overlay while playing Cyberpunk 2077â„¢ on Radeon RX 6000 series graphics products.

Known Issues

– 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.
– Connecting two displays with large differences in resolution/refresh rates may cause flickering on Radeon RX Vega series graphics products.
– Radeon performance metrics and logging features may intermittently report extremely high and incorrect memory clock values.
– Cyberpunk 2077â„¢ may experience shadow corruption on Radeon RX 6000 series graphics when ray tracing is enabled.
– Disco Elysiumâ„¢ may experience texture flickering on trees with Radeon RX 6000 series graphics products.
– Radeon Software may experience a crash when Record & Stream tab is in use and a display is hot plugged.
– Radeon FreeSyncâ„¢ may intermittently become locked while on desktop after performing task switching between extended and primary displays upon closing a game, causing poor performance or stuttering. A system restart is a potential workaround if this is experienced.
– Performance metrics may incorrectly report temperatures on Ryzenâ„¢ 5 1600 series processors.
– The download or launch Ryzen Master buttons in Radeon Software may intermittently disappear or may fail to initialize Ryzen Master.
– If Ryzen Master is not detected in Adrenalin software after installation, a system restart maybe required.

AMD Link for Windows Known Issues

– AMD is investigating isolated reports of intermittent loss of signal during Stream Optimization if HEVC is used on Radeon RX 5000 series graphics products or later. A workaround is to use the AVC encoding setting instead.
– Intermittent grey frame corruption might be observed when streaming with HEVC on certain configurations via an Internet connection. A workaround is to use the AVC encoding setting instead.
