What's the model of your laptop? I think confirmation that you have a laptop using nVidia's GPU-switching Optimus technology would help us diagnose your problem.

If you know you have Optimus already, you may need to specifically configure some games (like FFXIV) to switch to your nVidia graphics card from the lower-power Intel one when they run.
