MisterMonster thank you for the update.


Have you tried changing the resolution of the game window? Check whether the game is running in fullscreen mode, windowed or borderless fullscreen. Fullscreen is generally more efficient when using GPU resources.


Please also try doing a cleanboot boot by going to the 'Config' option on the Final Fantasy XIV launcher and to the right of 'System Information' click on 'Display.'

Hope to see you online!
