Thank you for posting in the Final Fantasy XIV Technical Support Forums.

We apologize for any inconvenience you may be experiencing with game crashes. These DirectX crashes may be caused by a variety of issues.
We first suggest lowering the graphics settings in game, as the intense graphics in dungeons can cause the game to crash.
We also suggest updating your graphics card's drivers to the most recent version.
If the crashing persists after attempting these solutions, please make a post in the official bug forums so the development team may review the issue.

This thread will be moved to "Closed Concerns”. Thank you once more for visiting the Final Fantasy XIV Technical Support Forums!
