Battlefield 1 lag,spikes Fix?

I just download BF 1 like 2 days ago, and i play it like just 1 hour got so many FPS Drop and only got like 20-30 fps on low settings, Yes i've disable origin in game,set my BF 1 to high priority, still only got 30 fps ish.
But i have playing BF 4 like 2 month nothing problem on High setting (really smooth) i was wondering if u guys can help me with these problem cause BF 1 almost unplayable.
I've trying google it nothing really helps, thats why i made post in here cause might u guys can help me.

I read about bad nvidia drives causing some fps issues. Do you have an Nvidia Card? Maybe you already fixed it since this is pretty old already.
