FFXIV, DX11 and multiple screens gameplaying

Subject - I use Actual Multiple Monitors to use 2 monitors. One for FF, second for open browser. There is an Ignore Focus Lost option in this software, which means game won't minimize to the taskbar when u click on 2'd monitor. And with DX11 on it doesn't work at all. Only with FF I must tell u. Besides after getting Extremely High with benchmark I'm not very bold with 22 fps if ANY water is around and I have tesselation turned high. Etc etc... Basically I cannot see any video improvements with DX11, only FPS losses. ONLY with FF! Any other game using DX11 works fine with all the DX11 coockies turned on giving me stable 55-60 fps.
P.S. So sigh.. Back to DX9..
