Could someone help me understanding why Daz skips my GPU and moves onto the CPU for rendering? Is it simply that 8GB is too less memory for this particular scene?

    Not enough RAM on the CARD; one of the WARNING Iray ERROR lines close to the end tells you why it failed.

    So 4194304 is what you need, but 3496345 is what you have. That's not a huge difference. See if there are some parts of the scene you can delete (things that are off camera, etc). Also, people in the background probably don't need textures, you can't make out the textures from that far anyway. Your geometry memory consumtion looks really high. Do you have subdivision turned way up on some of your figures? That uses a lot of extra memory.

    Yeah I kinda figured that. I had some parts which I could remove off the scene and once I did that, it worked like a charm. Thanks anyways.
