Thank you for the reply Kyomu.

Does this happen consistently (like a rubber banding effect), or does your the issue come up for a moment then go away? It sounds like you are losing control of the controller for a second and then it goes back to normal. Just clarifying.

When did this first start happening?

I would suggest a clean boot. Simply open the task manager and select the 'Start up' Tab. Disable everything here and restart the PC. This will make sure that no background processes are interfering with the game. Make sure you don't have any other programs running in the background while playing.

Also try to recalibrate the controller in the in-game menu (if you have not done so already).

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