Thank you for the reply jjajja.

Is it possible to start the game in windowed mode, then change to fullscreen and play normally? Or does it crash again when you change that setting?

You may be experiencing more lag because the DirectX 11 mode has some additional visual features. Does turning down some of those settings make any difference?

Try setting your laptop to a high performance mode if you have not already. Additionally, go into the Nvidia Control Panel and find Final Fantasy XIV. You should be able to assign the GPU for the game. Select the 960M if it isn't already.

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