It's been months since I switched back to DX9 because of this problem. I have tried every graphic setting possible,reinstalled the game, checked that no overlay programs are on while playing plus having my graphic card drivers up to date, nothing worked. Usually screen starts loading until it suddenly stops. If I click or something I get the usual "FF XIV is not responding " but if I let it be for like 5 minutes I get a 90001 connection error. I have no problems running this game on DX9 which really bugs me.

My PC specs are:
Windows 10 Pro 64 bits
ASUS M5A 78L-M LX3
AMD FX-8370E Eight-Core Processor
8GB RAM
RADEON R7850 TWIN FROZR 2GD5/OC
