UE 5.4 Settings for 3x RTX 4090 ?

Hello everyone!

I’ve been experimenting with Unreal Engine 5.4 on my workstation at work, which is equipped with three RTX 4090 GPUs. I want to leverage all three GPUs, but I suspect there are some settings I need to enable.

I found some tutorials explaining how to do this, but most of them focus on consumer-grade setups with two GPUs in SLI.

On my system, all three GPUs appear as a single unit in Windows, similar to a render server setup. Could anyone guide me on how to configure Unreal to take advantage of this?

Thanks in advance, and I hope to hear from you soon!
