Good morning and thank you for posting on the Final Fantasy XIV Technical Support Forums.

When does this error occur? Is it directly on log in? or is it while you are playing? If it is while you are playing, do you notice any pattern to it (when you are entering a new zone, accepting a quest, etc.)?

What kind of graphics card do you have? Do you have any overlays or other programs running while playing?

Any additional information will help us find a proper solution.

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
