I cannot play FFXIV Heavensward using the new dx11 client with my new r9 390x because the drivers cause the game to crash. Both 15.200 and 15.15 cause the same issue. If I remove drivers and revert to using my old r9 290x with omega drivers the game client runs fine.
I've tried numerous setting changes. I've duplicated the issue on 2 different desktops. I've even returned the 390x to the store and swapped it with an exchange to rule out the possibility of a hardware issue.
OS: Windows 7-64bit
