Low GPU usage

Hello, I’m setting up a Virtual Production set and my GPU usage is very low. I have raytracing on and a virtual camera that’s recording. I have a few lights that are both stationary and dynamic. While recording or editing the set my fps is low but my GPU load is also low. I wanted to know if there’s a way to set UE4 to use more of my GPU to compute the raytracing to get a better result. I’m using a RTX 3090 GPU.
