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

I'd like to get some more information about the issue you are having:

When did this first start happening? Did anything change or update on your PC that coincides with this?

Can you elaborate on the exact issue? Does the controller simply cease to function with XIV, or do you lose control of it periodically while playing?

Do you use the controller wirelessly or do you connect it with a USB cable? Have you tried both?

Do you have another controller that you test the game with? If so, do you run into the same issue?

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