Thank you for the information pribilof.

As others have stated, your Intel integrated graphics do not meet the minimum requirements for the game (and aren't officially supported). Switching to DirectX 9 mode turns off some graphical settings so it would make sense that you gained some frames per second by doing that. You will need to upgrade your PC (or in the case of a laptop, purchase a new one), in order to meet the hardware requirements.

Please be aware that the PC and Mac versions are not the same entitlement. If you have the PC version and want to play it on Mac, you will need to purchase the Mac version. Keep this in mind if you decide to purchase a new laptop.

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