Very small packaged project uses essentially 100% of GPU?

I’m very new to UE5, and while I’ve searched the forums, read documentation on packaging projects, and watched way too many hours of tutorial videos, I can’t seem to find what I’m looking for.

Basically, I have a very small project, more of a demo for myself for testing, and when I run the packaged project on a 980ti it is essentially at 100% GPU usage; when I run the packaged project on a RTX3070, it runs at about 90% GPU.

All that is in the project are five small levels using the default third person character BP, walls made of cubes, and each level only has the default skybox/directional light, or those are removed and there are 2-4 point lights in a level. The levels are extremely small; four cubes for walls and a few player starts and an exit collider blueprint.

When packaging, I only targeted windows, and I added only the levels I wanted to include in the demo.

I’m sure this is just complete rookie stuff, but I don’t even know where to start to figure out why this is using so much GPU. If anyone can point me to some helpful resources or has advice I appreciate it; I need to figure this stuff out now before beginning to actually build larger projects.
