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

It looks like your graphics card drivers are a bit out of date. Try updating them and do a clean install (This will be an option upon installation).

You can also 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. Additionally, close any other programs or overlays you might have active (Discord overlay, Geforce Experience, etc.)

Hopefully, one of these will resolve the issue so you don't need to reinstall.

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