Odd issue with Iray Rendering not using GPU

in Technical Help (nuts n bolts)

Hello, I've recently have an odd issue where the GPU isn't being used to render at all.

 

Seems i'm getting errors with GPU but have no idea why it's giving the errors.. it worked just fine in the past, and it works for everything else.

Going to try a clean re-install of the driver and see if that fixes it, any ideas would be great beyond that

    Unless you give some info on your Studio version, your specific GPU and the NVidia dirver version, folks can't be much help.

    Fastbike1 is correct, but I have the same/similar issue and have an open ticket with Tech Support, as described below.

    Bottom line: I upgraded Daz per Install Manager, lost ability to iRay render.  Again.  Same thing happened to many of us last year.

    ****

    Upgrading to 4.12.1.117 cancelled my ability to render (again). Can you please send me an installer for the previous build?

    This is the second upgrade where this has happened; last time it was fixed 8 months later with an eventual MSI video driver update. This time, I have the latest drivers and don't feel like waiting another 8 months.

    Specs:
    MSI GT62VR 6RE Dominator Pro Laptop
    Windows 64 bit
    48GB Ram
    NVidia GTX1070 8gb Graphics

    I'd be happy to go back to the prior version, if I cant get it.

    As for my OTHER 64gb, Win10, DUAL 980Ti,  32core, Daz 4.10.0.123 backup renderbox - it is NEVER getting upgraded, just for this reason.

    I read your log, and it seems your Driver may be newer than your Daz. 

    You are getting "The 'iray_optix_prime' scene option is no longer supported." errors, and the latest Daz has removed that option (iray_optix_prime) from the UI.

    So, uncheck that option and give it a whirl.

    If that still fails, try plan B: upgrade Daz.  WARNING: If possible, SAVE your current installation of Daz (copy the daz folder?) or it's installer before upgrading, then try upgrading to Daz 4.12.1.117, which Install Manager should let you do.  For me it was in the Upgrades list. (Boy do I regret tapping THAT.)  Again, this is because the latest Daz has removed that option (iray_optix_prime) from the UI.

     

    Good luck!

    I figured it out, thankfully it was just an odd issue with my GPU overclock, seems it was stable for everything but Daz.. lowered it a bit, everything working now.

    MSI does not make drivers. Your problem is almost certainly that you are not getting the correct up to date driver from Nvidia.

    I have tried it on 4.12.1.117 and it's not recognising my GPU either. I installed the most recent drivers, release on 27th May 2020 and it STILL won't work.

    This is the last of my log file, when trying to render with iray:

    There's no option any longer to untick OptiX Prime in DS so not sure how to fix this. I installed the update via DIM and it was working properly recently but now it's not and I don't know what to do.

    My setup is a custom built PC

    AMD Ryzen 5 1600 6-Core 3.69GHz processor
    GeForce GTX 980 Ti
    Graphic driver: 26.21.14.4614
    Driver Date: 15/05/2020
    16Gb DDR memory
    ​64-bit Windows10 Home

    The log says the scene exceeds the GPU VRAM.

    If you can't render a very basic scene, a single prinmitive with a texture then let us know.

    MSI does not make drivers. Your problem is almost certainly that you are not getting the correct up to date driver from Nvidia.

    VERY Good Point!!  -- I must have reinstalled the original 2017 driver.  (Also explains why my HDR output to the 4K went caput;  thought that one was the Microsoft Update's fault.)

    Let me try the latest NVidia.  I'll post an update after.  Thanks!

    HORRAY!   

    That worked like a charm!  -- Thanks, @KenShaw011267

    No. The first scene was larger than 6Gb and the second wasn't. iRay can only use a GPU if the scene fits in the cards VRAM.

    Except the first scene was not larger than 6gb.....

    That line there in the first one, means it ran out of memory. It did it right after geometry, which is when it loads in the textures. If you saved the first scene, you could try it after a fresh open of DS, if it drops again, you will need to do something about making the textures take up less memory. Personally I use the scene optimizer product when I need to do that, makes it quicker and easier than manually resizing and relinking textures in the scene.

    @Dark-Elf "Except the first scene was not larger than 6gb...."

    You can't tell how large the scene is in Iray from looking at the size on the HD or in CPU ram. Use GPU-z to tell you how much Vram is used.

    I figured it out, thankfully it was just an odd issue with my GPU overclock, seems it was stable for everything but Daz.. lowered it a bit, everything working now.

    hey which clock speed is good for daz. My daz is freezing cant render anything even my old scene which used to render properly
