1070 here
The Ti cards will have an edge over base cards.

I keep foliage off
Motion blur off
Depth of field off
Bloom off
View distance max

Holds a steady 60 at 1080
With foliage on it would drop a lot.. but its fairly solid with foliage off.
Game still looks great, check my screenshots.

A 1060 base card will probably not perform as well as this though.

Personally I think I wouldn't lower my settings anymore. I normally turn stuff like motion blur off anyway and no foliage makes it easier to forage for stuff.. So in your case I would probably lower screen res from 1080 and you should be fine.
