Thank you for the reply Mathak.

I'd suggest some of the following in order to try and alleviate the issue:

1) Update your Windows Operating System using Windows Update. Make sure to install any optional updates as these aren't installed automatically.

2) Disable any overlays (Geforce Experience, Discord overlay, etc.) that may be present while playing the game. Also make sure to close any other programs that are running alongside the game while playing.

3) 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!
