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

Do you recall anything changing or updating on your PC that coincides with this?

When you say "very choppy gameplay" are you referring to a lower frame rate or some kind of lag/latency?

Does this happen everywhere, or is it confined to a few areas?

Can you submit a Final Fantasy XIV system report? Simply go to the 'Config' option on the Final Fantasy XIV launcher and to the right of 'System Information' click on 'Display.'

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