So i'm in the market for a new GPU in the upcoming months and i was considering to get a 3080 or 3090 because as it looks right now Optix and CUDA are the only development focus.
Is there any chance for OpenCL, Vulkan or any other API support that includes AMD GPU's when it comes to Arnold GPU?
The last statement that i heard was from a couple of months ago where @Stephen mentioned that Optix is the main focus right now.
Even though i understand that the industry and requirements are constantly changing a official roadmap similar to pilot testrun of the 3ds Max Roadmap would be helpful. Even if it just includes barebones information.

The roadmap is Optix.
Anything is else is maybe one day, with no ETA, and no specific plans at this moment
Any ETA for Optix? And are you planing for hybrid mode? aka XPU of Renderman. I tried iRay recently and was really surprised to see amazing speedup by using CPU+GPU there. Vray has little to no improvements when hybrid rendering is used but in iray speed increased in times. It's practically fastest renderer for today I tried. Excluding RT engines of cause.
Thank you.Arnold GPU (Optix) is already out. We're improving peformance and adding feature support with each new release. That's what we're working on.
Got it i'm definitely gonna go for nvidia then, thanks for clearing that up.
I think development is going good you guys are pushing updates almost every month with a big feature update every couple releases.
Do you have any ETA on Bitmap Lookup and OSL Environment issue that causes cuda errors on second render attempt when using GPU?
Just want to add that I would love to see Metal support on macOS someday. I know it’s quite the undertaking but the GPUs available for the new Mac Pro are amazing with the new Octane X. 4 GPUs with 128GB vram total is no joke. But the ease of use of Arnold and the constant development make it my favorite renderer to use even without GPU rendering.
The dream would definitely be the time to first pixel and interactivity of the current CPU renderer combined with the quick refinement of the GPU.
Now AMD GPU support ROCm+HIP API, which are nearly equivalent to Nvidia CUDA. Today Blender team officially announced for AMD GPU support.

So what about Arnold + AMD GPU ?
