Multi-GPU support for VR streaming

We are rendering a scene with Lumen and HW-Raytracing to an HTC Elite XR HMD that is getting the data via streaming. In the viewport we get 120fps but the headset is at around 25-30fps.

The headset has a resolution of 3840 x 1920 only, so I fail to see the actual reason for the performance drop but, since the data is streamed therefore independent of any physical connections.

Would it be possible to distribute the load to a second or even more GPUs in order to get higher frame rates?

Hi @Matt_F.Judge ,
For anyone else to answer this correctly you need to tell us are You using the same graphics controller for the VR, which would slow down if you have your monitor connected to same graphics controller. What graphics card is driving the VR headset. Nvidia RTX what for RTX 3080 with 24GB ram I hope.

Have you followed the guide for V5.3.2.

Lumen Performance Guide for Unreal Engine | Unreal Engine 5.3 Documentation

Screen Space Reflections in Unreal Engine | Unreal Engine 5.3 Documentation

I did once have a VR headset and had to put it on a seperate graphics card to get the fabled 90 FPS for a game to work.
Perhaps someone will tell you how they did make it work

Many requests have been made to convert and host the
HTCViveTemplate for UE 5.3
So its here now enjoy😁
