Hooked software isn't a bad lead for some possibly. I personally don't have any apps running in the background. However the vast majority of your other possibilities would all become easily apparent to us, sense I'm sure most have many many other games they play, that require all of those things to be in check. And no other game has a issue like this. And sense FFXIV was late to the party with DX11, its not a issue due to other games not using DX11.
