Multiple RTX GPUs to speed up rendering with raytracing

Hi,

I work for a company that builds highest end Servers and Workstations. We have a customer who wants to have the fastest possible solution for rendering highest resolutions and heavy raytracing in Unreal. What both he and us would like to know is, if a multi GPU system with like 5-10 Quadro RTX8000 cards would be usable in Unreal, or if we are limited to just one GPU. As this would make a great impact in their workflow and time management when they’re working on (Hollywood Level) movies and other virtual productions.

If someone could help us with that, that would be awesome.

Thanks in advance

I read somewhere in the site, in the documentation about SLI I think, that there’s a limit to the number of multi-GPU links and/or number of GPUs. But that article could be outdated, so I think emailing Epic directly about it would receive a faster response than the AnswerHub. Or perhaps in the Rendering sub-forum in the Unreal forum.
