VRayFastSSS2 Flickering

Hi!
Does anyone know how to stop the SSS2 Flickering in animations?
I tried saved Irradiance maps with 120/100 and even brute force with no secondary.
Its still flickering at certain distances to the camera.

The flicker looks like this (only the flesh layer, brute force with Adaptive QMC 1-6, 0.002):

I have used the milk preset and modified the color and scale multiplier.
Scatter GI and Trace reflections are turned on.
Single scatter option = Simple.
The rest is default.

It looks like the prepass rate for the fastsss2 material is too low.

Best regards,

Thank you!
It was indeed the prepass setting that was causing the flicker.

I was able to render it flicker free before the deadline
with the prepass rate in the Material editor set to +1.
