Daz 4.11 stopped using GPU

Member_257874

I just finally updated Daz from 4.10 to 4.11. But since I updated, Iray is not rendering GPU anymore. I have a 1070 and a 660 Ti. I have all three (2 GPU and 1 CPU) selected in the device tab. But it's only running on CPU no GPU:

GPU-Z reports no additional memory usage.

I double checked that I have selected all devices before rendering. They are active in photoreal and interactive.

When I select one GPU only, it renders a black image.

What's going wrong here?

Have you tried updating the drivers for your cards? 4.11 requires a fairly recent version of the driver.

I thought I have the latest, I will try that

Ok it seems I didn't have the latest installed. Works now, thanks
