Unable so far to get OpenCL working on NVidia. Did I miss the solution, are we even sure this can work at all?
@3DIO
The final command must be something I've installed then. Try inxi -Fxz
Tell me what it says re. your GPUs but I think you might not have installed the drivers properly. At no point was this ever going to work just on its own, but you do need to get the drivers installed as a first step.
@bluejaunte
dForce works out of the box with nvidia-libs on Nvidia hardware but I've never tried installing Daz Studio via Steam. It's a novel approach and I suspect that's what causing you problems :) You can either get Studio running using bog-standard system WINE (make sure it's v.10 or greater), or via a WINE manager like Lutris. Symlink the CUDA libraries by simply running the installation script as described on the github page and everything will just work: dForce, iRay, and the denoiser.
Oh ok, will try that. I didn't install anything, this is Daz Studio installed on Windows started through Steam/Proton. The idea is to get the speed of Proton that makes gaming possible today. Or am I misunderstanding that completely?
@bluejaunte
Hadn't realised you were using Steam to run Daz Studio. I didn't even know that Daz Studio was on Steam. I had no Steam or WINE installed at all when I first installed CachyOS, and it was basically Lutris that handled everything to do with installing whatever needed to be installed to get Daz Studio working.

Ah, that one worked fine and it does at least look positive in so far as it recognised my graphics hardware (Copy and Paste below):

I don't know if that approach will work but I think it's going to be problematic. I very much doubt the steam runner includes Optix and OpenCL, but I don't know for certain. I can, however, guarantee it will work if you install Studio via DIM (or the complete packagae executable from your product library) from within your Linux OS. If you follow what I suggested for 3DIO earlier, all you'll need to do additionally is grab the pre-compiled nvidia-libs package from Github, and then execute the install command from the terminal. There are full instructions on the web page itself. Should be child's play for a man of your talents :)
@3DIO
I remain unconvinced it's working (looks like the default Linux AMD driver to me), but there's an easy test. Install Blender, head to the system preferences and see if you can assign your 580. If you can't, you don't have the rocm stack installed.
Daz Studio is not on Steam. You can manually add whatever game or software to it and it will run through the Proton layer. Which I assumed has the most performance benefit (not for Iray of course, just the general viewport performance).
@TimberWolf
Ah right, bit beyond me that stuff, but as far as Blender goes, I assume you're referring to this screen. I should point out that this never worked on Windows either. I used CPU rendering on Windows just as I'm doing on Linux. Nevertheless, my dForce did work on Windows despite the Blender thing being exactly the same on Linux.
@bluejaunte
I understand what you've done. I just don't understand how you've managed to tie the (essential) nvidia-libs DLLs into that setup properly. Anyway, I didn't find any particular runner gave an advantage in terms of viewport performance. 4.24 on my system is running on system WINE (11.7), and 6.x is running on proton-cachyos-slr. The viewport performance in the Beta is pretty woeful even in Windows and the only reason it's still on that runner is I neglected to change it back to sys-wine.
I can't tell you how to get it working in the configuration you're using I'm afraid. Give it a whirl in Cachy itself - I doubt you'll find the viewport is any different in how it performs on Windows.
@3DIO
I'm showing my lack of expertise as well here. I didn't realise it had to be an RDNA card for rendering which yours is not. The only thing I can suggest is to join a Cachy forum and ask people who will be experienced with AMD hardware how to get the ROCm stack and OpenCL (Rusticl is probably what you'll need) working properly. I doubt any will have experience of Daz Studio but someone on there will be able to point you in the right direction but I have my doubts this will be successful.
Still, all it will cost is time and you'll undoubtedly learn a lot. I am not really the person to speak to for AMD stuff.
