It is not possible to deform dynamically the terrain with correct performances.

You can modify a zone in real time (for exemple, move some patch vertices)
but once done, it will have no effect till you invalidate the patch tesselation 
you have modified.
And the tesselation invalidation will block the next render pass for a long 
time (depending the zone 
complexity), because it will have the recompute all cached tesselation.
In the render pass, the tesselation is updated with a complex incremental 

I'm sure it is possible to adapt current algorithms to this problem, but it is 
not an easy task.
