Guys know of some grass mod for fallout4 that does not consume FPS, install one but had a descent of horrible fps, despite having the GTX 1060 of 6GB a card but that to spare to move FO4 to 60 fps, if you do not know to which mod I mean illustrate with a video

A mod of grass type this but that is not a devourer of fps or at least it stays stable to 60 fps:...

I don't understand entirely what you are looking for. I know you mean grass mods but I don't know if you want a crazy amount or just little touches of grass to your world. 

I guess I will just include a list of grass and tree mods that you can pick from.

Grass Mods:
Grasslands - A Fallout 4 Grass Overhaul
Lush Landscapes 
2RTR - Greener Grasses
Fallout 4 Seasons - Grass - Trees - Plants - Snow

Tree Overhauls:
Commonwealth Conifers Redux
Springtime Trees

These are just some well known examples that should be OK to use. If you are experiencing to much lag when using these mods you could try lowering god rays and/or shadows to see if that changes anything. You could also try using FPS dynamic shadows - Shadow Boost as it loads shadows at a far without such a crazy performance cost. Gopher has a very good video showing you the features, setup, and use of the mod.

Also note that some of these mods may change both trees and grass so you may only need one. So always read the description before downloading more then you need.

@MrEggs0925 So I ask, there are so many mods of grass that I just want a simple one that does not consume resources, regarding the rays of God, I have my configuration of fallout4 everything in ultra, except the rays of God (desactivate) and the distance of shadows with the medium preset
