Quixel Megascans Foliage Help (FPS killers)

Development Rendering
1

So I have been trying to get into Quixel megascans for foliage and I can’t figure out why it’s taking up so much fps…

-I’m using 2k textures
-My Material consists of Albedo,SSS, and Opacity maps
I used blender to make LODs and have even further decreased triangle count in UE4

Here is one screenshot with FPS on.

FPS stats:

Fullscreen in editor at screen resolution 100% my fps was under 60 fps
Fullscreen in editor at screen resolution 200% my fps was under 40 fps

In the scene there’s roughly 900 instances of foliage

How are the LODs and cutoff points? How is your shadow casting set up?

Sorry, I haven’t checked this forum I made at all, but if you are still interested the LODs goes from 500 triangles being extremely close up to where only a few are at LOD 0 and then it gets down to 5 triangles the farthest away. I don’t know what you mean by shadow casting but my shadow cascade is at 3 and I also have ray-traced shadows enabled.
