Greetings Adventurer!

You may want to try setting the priorities higher for Final Fantasy XIV. While the game is running, please open up task manager and click 'Details'. Find the game and right click it to select the 'Set Priority' options to 'High'. Additionally, we would suggest that you 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 visiting the FINAL FANTASY XIV Technical Support Forums!
