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

- Make sure that the Windows OS is fully updated
- Switch between full screen and borderless windowed modes.
- Please try adjusting/lowering the resolution.
- Please try running the game as an administrator

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.

** Open the Nvidia Control Panel and go to 'Manage 3D Settings'. From here, select 'Program Settings' and select Final Fantasy XIV. You should see an option to select the GPU. Make sure it's set to your dedicated graphics card (it may be set to 'Auto' by default)

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