Hello,

I was trying to set up an Unreal Engine Project with nDisplay where I want multiple PC’s to render with ndisplay. I came accross this documentation from epic games about synchronisation with nDisplay with nvidia GPUS: [nDisplay Synchronization with NVIDIA GPUs in Unreal Engine | Unreal Engine 5.7 Documentation | Epic Developer Community](https://dev.epicgames.com/documentation/en-us/unreal-engine/ndisplay-synchronization-with-nvidia-gpus-in-unreal-engine)

There it is stated that this setup requires a mGPU setup and not a multi process setup. On the epic forums documenation about multi process rendering it is stated that mGPU is supported up to Ampere GPU’s. [Multi-Process Rendering with Unreal Engine | Unreal Engine 5.7 Documentation | Epic Developer Community](https://dev.epicgames.com/documentation/en-us/unreal-engine/multi-process-rendering-with-unreal-engine)

So me it seems like the documentation might be deprecated and I would like to ask one your experts. My Question would be If I want to use a cluster of multiple PC’s with Blackwell GPUS using the Nvidia render sync policy would I use a mGPU or an multi Proecess setup?

Thank you for your help.
