sure thing. I have never seen Goldorak or anyone else on team state that AMD GPUs are guaranteed (now, or ever) to be as powerful/stable as NVidia GPUs in Octane. I'm not a betting man.. especially when deadlines and/or money are involved. But at the same time I will admit that I have not researched this, and I am just going by me not remembering any promises where AMD GPUs and also CPUs are concerned. Maybe supporting things other than NVidia GPUs in Octane will be just that..
supporting them.. I dunno. I'm sure someone will set me straight.
I have to agree with the above.
When using Octane 3 for production ready rendering, especially on a deadline, please keep in mind the following guidelines:
1) Never rely on features that are not yet supported in Octane 3 with the latest stable release for your host application
2) Never assume peak performance or stability using hardware that is not supported in Octane Bench V3 or later. We only add a GPU to OctaneBench once we are dune tuning Octane on the supported architecture and all is stable.
AMD support is very experimental right now, and I don' see that changing until we are at least a few releases after the first drop to users. We have spent a lot of time just making sure that very first release is feature complete and doesn't crash. I'd be surprised if we are ready to add AMD GPUs to Octanebench any faster than we did with Pascal GPUs (which were much simpler to tune than AMD w/ cross compiler). We will have months of performance tuning and (presumably) bug fixing.
