Iray Memory Leak; Nvidia Driver 566.36

Has anyone else noticed a memory leak in their Vram since updating to Nvidia Driver 566.36?

I am running a 4090 in Daz Studio 4.22 and after updating from 560 to 566.36 I noticed that if I do a batch render of an animation in iray overnight, since updating to the new driver, I will check it and see in the morning that my GPU memory has filled up completely and it has bounced the render to CPU. I have to close and reopen Daz Studio to clear out my Vram and then I can finish the batch render.

I was able to do similar batch renders before I updated the driver without this issue. Am I the only one with this problem? I'll likely rollback.

    This driver problem has been discussed in several forum threads here. The advice is to roll back.

    OOOOH, ok, good to know, thank you. I already rolled back to my previous version.

    As long as the version you rolled back to is equal to or higher than the minimum required by the DS version you are using, you are OK. If it is working OK for you, just continue on, I'd say. Finding the actual documentation of what driver version is the minimum required is a little difficult IMO. I'm using DS 4.23.1.23 Public build (Beta) with driver 560.94. I don't normally do animation. I haven't had a problem with this configuration for the still renders I do.
