Thank you for the update Itsuki_F. I apologize for the delay in my response.

You mentioned you have your drivers up to date. Did you do a clean install of them? This is an option you have when you install/update them.

Do you have any other programs or overlays (Geforce Experience, Discord overlay, etc.) open? Try disabling anything you don't need to pay the game.

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.

You may want to try stetting the compatibility mode to Windows 7. Right-click on the ffxivboot.exe file and select ‘Properties.’ Then select the ‘Compatibility’ tab and choose Windows 7.

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