Will other graphics processors be included to help boost speed?

It seems the Iray side if things is faster if you have nvidia but painfully still slow if you are running a radeon and the open gl is stripped down everything....will any of the other cards see some speed love???

    Iray is owned by Nvidia so they only support their own cards.

    daz could use the cuda to openCL automatic translator >> http://chrec.cs.vt.edu/cu2cl/

    Not surprised that AMD would be behind this 100%, lol.

    AMD used to have a big thing about it on the developement site coming upto the vega release and EPYC supercomputers

    That sucks! So even though I have a pretty beefy computer....I am back to the graphs card pissing contests if the 90s!

    Not at all, unless you chose to; you could use other renderers, including the other one integrated into Studio.

    The open gl rendering is very basic and 3D Delight isn't in the deep down options anymore.

    Deep down options? Do you mean drop down? It should be there. (just checked, it is there for me.)

    Are you looking in the right place? The big wide button with the drop-down list is (I think) at the top of the Render Settings pane.

    Note that the Render Settings pane used to look very different several versions back; it confused me for a while, since the render engine selection used to be very much more obvious.

    I can't afford to replace my AMD FirePro with an Nvidia card for the foreseeable future, so I'd love to be able to use ProRender.

    Many GPU based renders are written for CUDA, meaning they only work with Nvidia. Why? You have to ask them, but CUDA is very popular. It would certainly be nice if Daz had an AMD option, but it is what is. You can export scenes to other render engines.

    It could actually be worse. Iray uses OptiX, and the main version of OptiX is a pure GPU renderer, it has NO CPU fallback. But thankfully Iray has a CPU fallback mode, otherwise the AMD users would not be able to use it at all. The new Iray in 4.12 is actually using Intel Embree for CPU rendering.

    One more note before I go, Iray is limited by VRAM, if you exceed VRAM the entire scene is dumped to CPU mode. So do not go out buying a small 2gb GPU for Iray, you'll always be running out of memory, and it would be largely useless for practical rendering. So make sure whatever you buy is large enough to handle the stuff you tend to make.

    OTOY Octane is a good option, there is a good DAZ plugin for it, and it is very fast ( faster than Iray ). Only down side to it that I see is that, whilst the DAZ plugin does a pretty good job of converting Iray materials, it will insist on adding a specular component to a lot of materials, and what's worse is it by default drives the diffuse base colour and the specular colour from the same source ( usually white ), so things render glossy which shouldn't.

    It's easy to add a separate source for the specular, and set that to black, it's just a bit annoying.
