Displacement map acting very weird

Hello all,

My displacement map is acting weird.

I have downloaded some mountain maps from internegt and want to connect the displacement map as you can see below. I think nothing wrong there.

Changing the level of detail higher I get these weird looking circles. The higher i set it the more circles I get. Obviously, I can't go with 256x256. I need the 8x becasue the map is also 8k.

Look at these results. It does not matter if I set the height to a low value or to a high value.

As you can see, it does not have to do with how high the height is. There is always these circles.

I tried it even with a map of my own:

Can someone please let me know what is happpening?

Thank you!

Hi,
are you using 8bit depth textures for Displacement?
Texture Displacement loves textures at 32bit depth.

Did you tried with Vertex Displacement instead?
