Hi guys, have these kinda little tiny squares all over the game. Anyone here know what it is or how to fix it?

i also do have that in other games, but not as visible as in Final Fantasy.

My PC Specs are:

i7 4770k 3.5ghz
Direct x 11
GTX 780 4gb OC edition from MSI
16 gb 2133 mhz of ram from traumatizr
motherbord is MSI GD 65 z77

Would love to get some help, cause just bought this new pc.
and send it into reperation 2 times already :/

i will send a link to a screenshot showing my ingame graphic fails.
