DAZ Iray not using GPU to render

Hello! I'm having a problem with the Iray renderer in DAZ. I'm using DAZ Studio 4.9, and my video card is GTX 570M (1.5GB) with the latest driver installed.

When I render just one Genesis 3 it renders fine in Iray. But as soon as I add a second figure or add more scene elements and try to render, it stops using my GPU and uses the CPU 100%. This is the information from the DAZ log:

Iray INFO - module:category(IRAY:RENDER):   1.0   IRAY   rend info : Rendering with 1 device(s):

Iray INFO - module:category(IRAY:RENDER):   1.2   IRAY   rend info : Falling back to CPU rendering.

Is my GPU just not strong enough or is there something I can do? I'm not even using a lot of scene elements... just two figures, hair, simple clothing. No background or furniture.

Any information would be much appreciated, thank you. smiley

    Well...your scene is over the amount of memory you have available...by almost 2 GB.  So if you have 4 GB of memory for the video, the OS and other programs are using 1.2 GB worth of it.  But even 4 GB of memory wouldn't be enoug, as the scene is weighing in at close to 5 GB.

    You could drop that some by enabling/lowering the limits with texture compression, trimming items from the scene, lowering Subdivision levels and breaking it up into pieces to render in layers, but I'm not sure you can reign in around 2 GB worth of it.

    It's the memory. If the scene exceeds the memory on your card it drops to CPU. With all the maps for texture, bump, sss, displacement, etc... 2 clothed G3 figures can exceed 2gb.

    Ah thanks guys, I guess I need an upgrade then. I'll tough it out with the CPU for now. Just wish it didn't have to run at 100%.

    Not sure if I should start a new thread, but I also have a problem with my nvidia card not rendering. I have an asus z87 plus motherboard, i7-4790k processor, 16GB system ram, nvidia 1050 ti with 4GB of ram. The graphics card is checked under photoreal and optix prime acceleration.

    What version of Studio Help > About Daz Studio?

    I was using the current release; I didn't know about the beta version. Things seem fine now using the beta. Thank you.

    Then how do we do the texture compression? And how do we know how much ram my file worth? . .…………………………………………………………… . . .
