Fixed the slices, but had to extend out the distance to 500. Basically hiding them out of view.
Changed setting on the material instance to the following
Tessellation Distance = 500.0
Tessellation FallOff = 500.0
Tessellation FallOffCurve = 1.0
Tessellation FallOffDistance = 2.0
Hit me for a 10 fps more loss.

To accomplish this i had to extend the distance out to 500 which took the tessellation out a bit picto show how far out it goes
Going to mess with setting in the height function to see if i can fix the slices to bring the distance back in some.
EDIT: NEW SETTINGS TO FIX SLICES
Tessellation Distance = 150.0
Tessellation FallOff = 150.0
Tessellation FallOffCurve =0.2
Tessellation FallOffDistance = 0.9
Seems to be about the best settings
Edit: settings change from editor to game, so you will just have to play around with the numbers until you find happy medium. Good luck with this if using it. Slices are a pain to get rid of. Also dropped 10 to 15 fps with this enabled.
After trying lots of different things today to get rid of the slices in the mesh. I found OUT A FEW THINGS THAT DO NOT WORK AT ALL. If you try and take the R and G channel from the normal and add them to make displacement. It will not work right, causes to many points or jags with tons of white spots. The secret to getting good results is coming up with good displacement map or texture. Once you have made those properly you will get good results. As in the formation of the mesh being properly made to match the material.
