Radeon Software Adrenalin Edition 21.2.1 Released By AMD

AMD Radeon are starting February strongly with an update of their Radeon Software Adrenalin Edition driver package, helping to smooth out the launch of new indie horror title The Medium on PC. Alongside performance improvements tailored to that title specifically targetting the RX 6000-series, these drivers also roll-in a handful of bug fixes and solutions to little niggles Radeon users might be experiencing.

The Radeon Software Adrenalin Edition 21.2.1 offers up to 9% performance improvement in The Medium, as tested with a 16GB Radeon™ RX 6800XT graphics card @ 4K resolution, when compared with the 21.1.1 driver. This sort of figure is nothing to be sniffed at, but in this launch window knock-on benefits to minimum FPS and overall game instability are perhaps even more critical (as is the case with all major titles). Hopefully these drivers will alleviate any underlying issues early-adopters might be having.

Fixed issues however run the gamut from specific conflicts with MSI Afterburner to Samsung CRG9 series display's infrequent 'black screen on wake-up' problems. Seven are highlighted as major in the release notes, but many less noteworthy may well have been addressed with this release.

AMD also take this opportunity to identify five major ongoing issues which are now on their radar and will hopefully be squashed in the not too distant future.

This RSAE release is available to download from AMD by inputting your specific hardware and software configuration with separate installers for 64-bit versions of Windows 7 and 10. Alternatively, download via the Radeon Settings desktop app. AMD are transitioning to the RX 6000-series for their touchstone hardware but this driver supports Radeon GPUs are far back as the HD 7000-series (GCN 1.0).
