Thank you for the reply Shiftedd.

There are a couple more things you can try to alleviate the issue:

-Switch to DirectX 9 mode (select ‘Config’ from the launcher)
-Set compatibility mode to Windows 7 (right click on the exe file and select ‘Properties.’ Then select the ‘Compatibility’ tab and choose Windows 7)
-Make sure that any anti-virus software they have has the appropriate exceptions
-Install game on C drive if it is not already

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