Good morning and thank you for posting in the Final Fantasy XIV Technical Support Forums.

The FPS drop can be caused by a couple different things. Have you tried lowering the resolution or the settings preset? Reducing them should help you get more frames per second. Also please try running the game on " windowed" mode. Another thing you can try is disabling full screen mode. 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.


Hope to see you online!
