In my scene further sub-dividing the mesh was the most significant factor for improvement.

The image I used was already 7k, 32bit, float with a slight blur on the tick to reduce the edge sharpness.

Yep, that's it!!!!

Can't believe I didn't think of that as a solution.

I don't think that was covered in the tutorial but it feels like the most important part of the process to me.

Thanks a lot for your help atome451!!

Thanks for the quick response Aoktar.

The image that's driving the displacement is 2K but I've tried it at it's original size of 7k and it's the same result.

Can anyone tell me why I'm getting this aliasing problem around the edge of the tick?

The level of detail here is 8k, it's driving me crazy as I've got a mega tight deadline.

This is what I'm shooting for...

Any help smoothing the mesh would be greatly ...
