First time user, installed the latest Daz, but Iray does not work only with CPU. Tried clean installing the latest Studio driver after DDU, but nothing changed. It can clearly recognize the GPU, but logs still say that "found no usbale devices". Anything I can do?

 [WARNING] :: \src\pluginsource\DzIrayRender\dzneuraymgr.cpp(373): Iray [ERROR] - IRAY:RENDER ::   1.0   IRAY   rend error: Cannot render: found no usable devices. Please update your NVIDIA driver (www.nvidia.com) to at least 537.13, or enable CPU rendering.
 [ERROR] Iray :: Invalid parameters (NULL pointer).

    50x0 cards cannot be supported by Iray in DS 4.x.x.x due to the way the code has been compiled (Daz gets a finished set of modules to which it links, it doesn't get to compile its own).

    DS2025 alpha can use 50xx cards for Iray rendering, so a workaround could be to use your DS4 to create the scene, then the alpha to render with Iray.

    Thank you both! Actually the work in DS4 and render in DS2025 is smart approach. But as a Daz beginner, not sure what view I should use that's closest to the Iray so I can kind of see what the final result would be like without switching from the two apps constantly (something like EEVEE in Blender)?
