AMD has released the Radeon Software Adrenalin 18.10.1 Beta drivers. These drivers include support for Microsoft’s Windows 10 October 2018 Update as well as optimizations for Call of Duty: Black Ops 4. Along with improved support, AMD has addressed a number of issues with this latest release. First of which is a fix for the HDMI audio drivers not upgrading during the Radeon Software installation in some circumstances. Random reboots when upgrading from Radeon Software versions older than RSAE 18.8.1 on CPUs with more than 16 cores has also been resolved. In regards to gaming fixes, Fortnite sees lighting corruption when effects quality is set to High or Epic resolved, while Sea of Thieves sees texture flickering in multi-GPU configurations fixed.
