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

How long are you playing when you experience this? When the game closes, what error message (if any) do you get? Do you ever experience this kind of lag outside of the game (with Discord, for example)?

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

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