Render quality

[poliedrostudiosrl_poliedrostudiosrl]

Hi,
I noticed that the 1920x1080 and 3840x2160 render quality, with the same samples, is different. the smaller render has artifacts in the z-depth.
The result is better in larger rendering even with lower sample numbers.

1920x1080 (3000 smaples) vs 3840x2160 (1000 samples)

Can you attach example images of this ?
It will help us figure out what might be the cause.

Hi Valdimir,
Thanks for the reply. I can only attach a small detail because the 3d model is an industrial product. you can see that in the 1920x1080 image there are flickering.
You can download in this link.

Hm, interesting, do you have the denoiser enabled in these tests ?
If not, these are definitely NOT expected.

In any case, would you mind sending me the scene file as in the screen-shots ?
I need to play around with it to figure out what's going on.

Hi, the Denoiser is set to value only 10 for Hight and Low resolution.
Sorry but i can't send you the file because is a new industrial product of a famous car manufacturer.
