Flickering of the characters in the game in sli mode. (Dark Souls 3)

There is a problem. On my Lenovo y500 laptop with two 750m graphics cards running in sli mode, the main game is fine (keeps over 30 fps, with small dips in full hd). But in both add-ons in certain places (during and after the fight with her sister Frieda, in a pile of trash and some places) starts the slide show. Pomolodevshimi in the game profile through nv inspector and change the official bits on bits to Prey, I made a smooth image in the entire game. But here the misfortune, after I hit any mob, the character along with the body of the enemy begins to flicker until I sit down to the campfire or restarts. All foreign forums searched, no solution found. Maybe you need something else to change the settings through inspector? Who faced? While playing through off the profile of the scintillation present.
