Did a little research on your Laptop. Here's the problem. Your Laptop automatically determines which graphics card it should use based on a programming built into the NVidia settings.

The Good News - Your Lapotop will play FFXIV as soon as we adjust the appropriate settings.

The Bad News - The means by which to change those settings appears to be ridiculously complicated and will take a little while to decipher into reasonable directions..

I'll see if I can come up with some reasonable steps for you, but it might take a while. For now, I recommend you try looking around the NVIDIA settings for an option that blatantly says manually configure switchable graphics or something to that effect.
