It had one problem with DX9 that caused crashes. Disable an option fixed this. The crashing issues I have read regarding DX11 applied to both Nvidia and AMD. The Fury X bumped my average FPS by 20. It can be better with newer drivers. I have had no performance issues with the DX11 client except this small FPS bug. If I turn off the FPS cap, I can get over 100 FPS but that will be with tearing.
