Updated to Windows 10 April Release 1803 when it came out. Bought (for me...) a new R7 360, and updated the driver to the newest, 18.4.1. Oops. Rolled back to 18.2.1, looks like it is working now. What is wrong with the new release? Hoping I don't see the message again soon - "You do not have a compatible graphics card". Installed clean for this one; hope that makes the difference.
