Large brush sizes causes hitching in Landscape Sculpt mode

In my case I used the erosion brush and smooth brushes. 

Not a regression checked in Version: 5.1.0-23058290+++UE5+Release-5.1

1. Open any project in Unreal Editor
2. Create a new basic map
3. Delete the Floor mesh
4. Create a new landscape
5. In sculpt mode set your brush size to the maximum possible
6. Fly around for a little bit

Result: Every couple of seconds their is hitching

Expected Result: Smooth flying
