Problems with FPS

[Kerberon]

I use a 4k screen. Most the time I run @ 4k but even when I use 1080/120 the game will only use about 25% of the GPU's. When I use a single card then it will run 99%.

Sadly all the other games I play have no such issues.

That's because ff14 arr uses a directx 9 client with no support for multiple graphics cards. Trying to use multiple cards with crossfire etc is a waste of time because there is no support for it and it does not work, period.
