Well it did work for 2 days, but then it went all to hell again, keep constantly getting blackscreens of doom and then computer restarts.... that only happens with the dx11 client and with FF14 only. I changed back to dx9 again, and have 0 issues with it. Unfortunately there is something very wrong with the DX11 client.

Ive investigated a little and a lot of other people are getting problems with it too, interesting tho its the majority having problems are the ones with new Nvidia cards, the 900 series. I have a 970 myself.
