Using the latest drivers from Windows 10 1903 update center I got a very strong performance drop and freezes (30-40% hit in GTA 5, DbD and Fallout 4). Are there any solutions to this problem?
You have to furnish some more information https://community.amd.com/thread/196209
1903 insider preview, report it on MS hub.
Use the latest official build of Windows, 1809.
Problem fully solved by installing driver version 19.4.1
