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

Do you notice any pattern to this issue? Does it only happen in certain places or while doing certain actions?

You may want to try some of the following in order to alleviate the issue:

1) Disable any overlays you have active and close any unnecessary programs.

2) Try 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.

3) Do a clean reinstall of your graphics card drivers.

4) Make sure your anti-virus has the appropriate exceptions for Final Fantasy XIV.

5) You may want to try a reinstall of the game. When you do, make sure to remove the locally-saved data folder (located My Documents > My Games > Final Fantasy XIV). Be sure to make a backup of this just in case it doesn't resolve the issue.

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