Why does the game get hitches when the project is deployed but not in the editor?

Hello,

So i recently have been trying to deploy the packages ready for steam, It has Constant stuttering and hitches. When playing in any level such as a simple level with a few blocks i still get hitches/stuttering. But when running in the engine the project runs like a dream.

The project is also fully made with blueprints.

Is there anyway to solve this?
