Greetings.

I upgraded from an old graphics card to a new EVGA GEForce RTX 3090ti and had the store install the card and the drivers.  Even when rendering a small scene (1 G8F, clothes, a prop bench, and a 4k HDRI), the renders are calculated by the CPU.  Obviously, something is up.  I am not tech savvy.  Is there an online checklist or something?

    Greetings.

    I upgraded my old graphics card to a new EVGA GEForce RTX 3090ti.  However, even for small Daz Studio scenes, the renders are dropping to CPU, not GPU.  I verified with a very simple 1 G8F and clothes, 1 prop bench, and 1 4k hdri.  Still rendered entirely by CPU.  See attached screengrab of task manager.  

    I am not tech savvy.  Is there an online checklist or similar to help me identify the problem?

    If you in Daz Studio go to render settings > Advanced, is your graphic card then listed there?

    What driver version  is actually installed?

    Task manager default display doesn't display CUDA activity, which is what Iray uses. Check the log file in DS to see if the card was used.

    Thank you for the quick and informative response.  How do I check the log file?

    Download GPU-z. It's a simple, standalone program that tells you everything about the activity on the graphics card. Start GPU-z, select the "sensors" tab, then start your render. You should see GPU Usage go to 100%.

    Here is some information from the help / video card and log files, but I don't know how to interpret it.  Does this mean that the render was done with the graphics card?  Or not?  What should I be looking for?

    It says that it is using yoir 3090ti for rendering.

    For another time, attach the log as a text-file.

    Thanks.  And will do next time.

    Agree with @felis, looks like the GPU rendered the scene.

    Also, in the task manager you had up, click the "Performance" tab, then click "GPU0" or similar name on the left panel.  That will show you your GPU memory use.  Apart from an install error (your logs show Daz recognizes the card), the only reason for a CPU render is if you run out of VRAM.  In that case, GPU memory use spikes near max around the start of the render, then drop significantly as the CPU takes over.  Alternately, the logs will clearly indicate that it's a CPU render.  Hope this helps and have a great day.

    if the gpu isn't rendering ... and you don't have a program like battlecoder shirase on daz... you'll know immediatly it's all on the cpu ... because unless it's been fixed the cpu render engine will use every bit of cpu cycles, running up to 100% gets a little difficult to do anything including stopping the cpu render
