Need Help With Lag Problem

[Beyondgrave]

Hi all, I've been getting lag randomly ever since I got back into ff14 a few weeks back. The game would run fine and then everyone would stop moving for a few sec or so and then everything that happened while I froze would catch up all at once ( example would be me casting a spell but my character won't do anything and then all the sudden she would cast 2-3 spell at 2-3x speed, kinda like watching a movie being fast forward.) This is weird because before I left, I never had this problem. This lag makes it really difficult to heal because I can't tell when people is taking dmg and all the sudden they would drop dead.

My specs are - Gpu-780 gtx sli, cpu- intel i7 4930k oc to 4.1, 16 gb of ram, OS - window 8.1. Internet speed- download-50mbs and up-10mbs. Any help would be greatly appreciated!
