An unexpected error has occured (DirectX issues)

[Mug]

I somehow got it to work. I deleted FFXIV (including the MyGames folder), then deleted my Nvidia drivers (and all other Nvidia software with it). I then downloaded and installed the latest Nvidia driver (I didn't install Nvidia experience), downloaded and patched the game, and now it works.

I am having the same problem. The client has become so unstable that I cannot play the game - crashes every 10-20 minutes.

And to add insult to injury, I cannot submit a ticket through the Support Site because I get the "the text you have entered is too long" error when that is clearly not true.

Windows 10. Occurs in various locations, when set to various classes - does not seem to matter. In a dungeon, out of a dungeon. Full screen, windowed. Nothing fixes it.
