Hello,

I already contacted the support. But there is still no solution.

After updating to Windows 11 the whole computer freezes while rendering complex scenes using iray. Even after downgrading to Win 10 the problem persists.

I re-installed DAZ Studio, updated all NVidia-Drivers but there is no solution yet. And no answers by the customer support for nearly three weeks now.

The system even freezes with graphics that worked fine before.

    Sounds a lot like dropping to CPU, your log is the best place to check.

    Also make sure you have enough Windows page file space available, that caught me out once...

    Best Wishes and Seasons Greetings.

    Yeah, the scene and Iray code (shaders, I think) might not fit into the available memory that is on your Nvidia video card.  See Daz Studio can render a scene with only one character and an HDRI background at a faster speed.  If this simple scene works then Iray renderer is able to fit the small scene into video memory/ram.  Therefore, Iray is using the CPU instead of the video card when you render larger scenes because the scene won't fit into video RAM.
