Vray GPU animation flicker

[nenad_jovanic]

Hello,
I have a problem with animation flickering. You can see the video below. I'm using Vray GPU, Light cache animation preset, for the lighting there is only adaptive dome without any HDRI. When I'm switching to Brute force, the flicker disappears but render time doubles, for the animation is a big issue. Also, I have some flickering white/black pixels (fireflies) only on metal and glass materials.
I hope someone has a similar issue and could help me.

You can find it at the link below.
Thank you

You can also try changing a setting under lighting from adaptive to full evaluation, this can sometimes fix those problems but will also increase your render times by a lot.
In saying that I still encounter flickering issues when rendering on GPU at times. Always in reflections or specular for me, it’s like the gpu version of Vray sometimes leaves out particular lights on certain frames in reflections.

Hi nenad_jovanic

Would it be possible to forward a stripped version of the scene with the issue reproducible through our Contact Form so we can investigate? Make sure to mention this thread in the email, thanks!

Hi @nikoleta.garkova, thank you. I will send you the scene. I have updated the graphic driver and seems better, but it still has a flicker. Especially on the specular pass.
