Running
I7 4770k OC to 4.3ghz
16gb DDR3 1866mhz
Asus maximus VI formula
GTX 780 3gb SLI config. (means i have 2 cards in my system!)

No changes were made to the system, no new installs, no nothing. only the FFXIV patch/hotfix that hit the week of jan 27 2014. once it was installed my FPS dropped to ......14fps...... this is a patch issue, i get no issues with any other game. Please review this SE!
