Grainy Display Depth Map in Cyberpunk 1.62

Set up ReShade 5.8.0 for Cyberpunk 1.62 (Raytracing Overdrive patch). 

Display Depth shows the map and normal in the right colors, but both are grainy and look like this:

app.picashot.co/shot/0c7323b3-9654-45c9-a020-3a4b38633281

The map and normal look the same at regular raytracing and with pathtracing enabled.

No DLSS active. Depth based effects such as Cinematic DoF work, but are out of focus. Fog effects look grainy as well.

Any idea what this is caused by?

In advance, thanks for any advice.
 

Check the "Copy depth buffer during frame to prevent artifacts" option.

Thank you so much!

Most of the effects work now!

However, Cinematic DoF can only create blur, neither auto focus nor manual focus works.

Display Depth now shows the depth map as solid blue and normal in solid white.

Does this mean the depth doesn't really work due to artifacts?

Anything I can do about those?
