Your problem is that this game is a complete kitten, I mean my specs are
I7 6700k
gtx 970
16gb ddr4
win 10
and i play all in very high and I cannot get more than 50-60 fps in lions arch, is totally bad optimization of this game because i can run games like witcher 3 on ultra above 60fps and this game is a crap if we talk on graphics. in other zones i get over 120fps but lions arch and the players consume lot of resources and makes you have low ping
