Greetings fellow Eorzean!

We're sorry to hear that you've been experiencing some technical difficulties with Final Fantasy XIV. For further assistance, we would like to request if you could provide a 'DXDIAG'. This can be done by clicking 'Start' on the Windows icon and click 'Run'. At the run line, please type 'DXDIAG', and hit "OK". Then click "Save all information" (in the DXDIAG window) and save it to a .txt file. Copy all that information and reply to this thread with it. Please also include all details involved with the problem for investigation on our end.

While we await your response, we'd also like to suggest the following troubleshooting steps:
- Try switching to DirectX 9 by selecting the ‘Config’ button on the launcher.
- Perform a clean boot by opening the task manager and select the 'Start up' Tab. Disable everything.
- Make sure that the Windows OS is fully updated.
- Disable Full Screen Optimizations. To disable this, please find the "ffxiv_dx11.exe" and right click it and select properties. Then under the compatibility tab there will be a check box labeled "Disable Full Screen Optimizations". Check it and click apply.

Thank you for posting in the Final Fantasy XIV Technical Support Forums!
