High OBS GPU Compositing Load

I've recently started trying to setup a 2PC stream using an elgato 4KX to let me move 2 camera and some ultrawide gameplay

In the scene composting 2 cameras and the game into a single scene, OBS will draw close to 30% load on my 3090TI which results in a fairly negative impact on gameplay.

Is this GPU loading normal for what I assumed would be relatively light loading?
Are there anyways to reduce OBS's footprint while running a 4k-60 canvas to my streaming computer?
