http://forum.square-enix.com/ffxiv/t...11000002/page2 There's a thread for this too. The problem began, for some, with the Windows 10 creators update and nvidia graphics card. I've had a completely new card installed and it's still doing this, so it's definitely a problem on ffxiv's side. As for a fix? Nothing seems to work and my system gets hard locked so. I hope s-e will look into this because I'm not sure what to do at this point personally.
