Greetings @barrybro

I’d recommend checking out this thread [unreal engine using all of my cpu and none of my gpu](https://forums.unrealengine.com/t/unreal-engine-using-all-of-my-cpu-and-none-of-my-gpu/591729) as there was a very knowledgeable user there that goes into a lot of detail on how/why the engine uses CPU vs GPU is varying instances. I hope that helps!
