Hi @Smolak

I just tried it on my test file with maximum clouds, enabled Shadow, and Fog, but still can’t replicate it. Can you send us this specific file? Thanks.

Let me know if you have sent it.

I noticed that I have this issue while frame generation is turned off. When I set it to Auto or On this issue is gone.

It can even render with fully clouds but without cloud shadows at all when frame generation is turned off.

Unfortunately it still flicker even with frame generation turned on :

Is this issue related to the one you have posted before? You did mention you’re enabling custom GI + Enabled the shadow

I tried using lowest settings for GI and reflection without success. Enabling frame generation was good before but when scene was growing, when I added many more object it started to flicker again.

This is not only flickering but while accumulation it can render just like without cloud shadows at all. It looks like cloud shadows are leaks Sunlight.

It was most probably caused by my custom Nvidia driver settings. When I reset them to default this problem gone. I hope :slight_smile:

Unfortunately it started to flicker again. It must be something random that cause this issue.

Strange but when I restarted D5 it works fine again. So it looks like it is not driver issue but something cause that there is need to restart D5.

Hi @Clov

This is big scene 2GB I will send it soon. Unfortunately when scene is small I don’t have this issue.

I found that it stopped flickering when I set DLSS version in Nvidia panel to “use 3d application setting”. Before I had - use latest :

I will test this more using default DLSS settings.

Still flickering, this is totally randomly, independent from any settings.
