Touchdesigner texture as driver for material attributes - world offset position

Hello. So i started out trying to use touch engine. I had no success due to the complexity of the setup and my lacking understanding of touch engine needs to be set up.

This led me to try out a simplified workflow where i simply feed Unreal with touchdesigner textures. It works pretty well and lets me work procedurally. My intend is to use unreal as a vj-tool heavily relying on its real time abilities.

Nevertheless, I had fine success establishing a great setup. See the youtube link.

BUT, despite feeding unreal 5 with a high res greyscale image the displacement looks jagged when being close at the object.

See the attached pictures of the sphere close up, the amount of sub d of the sphere, the textures resolution and the general material setup.

How can i overcome my issue? Should i go and use unreal 4 and see if the old displacement fits better (with dynamic tesselation)? I am also quite new to unreal with a background in blender, cinema 4d and touchdesigner.

Setup:
Touch texture → NDI → Unreal 5 NDI stream texture → Image used as world offset position.

All the best
