Hello Redname, Thank you for posting on the Final Fantasy XIV Technical Support Forums

To be clear this only started after the update? Please try the following suggestions:

Updating graphics card drivers/reverting to older drivers
Reinstalling game
Disabling background application and overlays
Switching to DirectX 9
Rolling back Windows update
Disabling Game Mode on Windows 10
Running as administrator and using compatibility mode

Hope to be of assistance. Thank you for playing Final Fantasy XIV! Hope to see you online.
