AMD's first graphics driver of July, Radeon Software Adrenalin 21.7.1, landed today with optimizations for EA's latest racer, the RX 6600M and 6700M mobile GPUs, as well as several bug fixes.

The Codemasters-developed racer F1 2021, the first game to arrive from the company after the EA acquisition, launched today, and those with a graphics card from the red team will want to upgrade to this driver to get the best performance.

While running the new 21.7.1 driver and compared to the previous 21.6.2 release, F1 2021 can see performance gains of up to 6% when raytracing is enabled, and up to an impressive 26% performance increase when it is disabled. The company's test bench for getting these results were running a Radeon RX 6800 XT GPU paired with a Ryzen 9 5900X CPU, while the game settings were cranked up to ultra at 4K resolution.

Here are the included bug fixes:

• An Oculus service error may be received on Radeon RX 5000 & 6000 series graphics products which prevents the Oculus Link setup software from running.
• Lighting corruption may be experienced in Apex Legends™ when Radeon™ Boost is enabled.
• Some users may experience elevated memory usage by AMD User Experience Program.
• A driver mismatch error may appear when two versions of Radeon software (Windows Store & AMD Support versions) are installed on your system.
• Some users may experience higher than expected memory utilization when running 3DMark Time Spy™.
• While playing Carrion™, some users may experience image corruption when Anisotropic Filtering is enabled.

The known issues list comes next:

• Game Compatibility advisor in Radeon™ Software Experience may incorrectly advise some users their CPU and/or GPU do not meet the minimum requirements to play some games.
• Resident Evil Village™ may experience an intermittent application hang or TDR on AMD Radeon VII graphics products in the first mission of the game.
• 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.
• If Ryzen Master is not detected in Adrenalin software after installation, a system restart may be required.
• If Blue or Black screen is observed in mobile systems, temporarily disable Enhanced sign-in.
• A Blue or Black screen may be observed after updating to the latest Radeon Software. A workaround is to disable core isolation.
• Lower than expected performance may be observed on select AMD Athlon™ mobile systems.

The Radeon Software Adrenalin 2020 Edition 21.7.1 driver is available for download via the optional section in the Radeon Software app on Windows. Standalone download links can be found on the driver's official release notes page here.
