Dithered LOD Transition on grass drops frame rate
I'm trying to improve frame rate by culling my grass. Checking "Dithered LOD Transition" in the grass's static mesh drops the frame rate.
Here, you can see it's high 30s (on the right) without Dithered LOD Transition.
Now I check the Dithered LOD Transition.
Now, you can see the grass is culled, and the frame rate has dropped to low 30s.
You can even see the polys weren't in the map when the shaders were compiling.
Why is this dropping frame rate? Is this a bug? How can grass be culled properly to improve fps?

Found the solution. I stopped using dithering LOD transition as that wasn't helping. I went into the foliage settings and selected the proper foliage type.

Dithered LOD transition is expected to reduce framerate, because overdraw in transition regions is significantly increased.
